He is an unbeliever who is either very ignorant or intellectually dishonest. Probably both.
About loving and hating everyone - Hating your parents, siblings, your own life, etc is not to be taken literally. It is a comparative term. You should love your family and your friends, but your love for God should be so passionate that this love you have for those people would be like hate in comparison. Jesus is not saying to love your family less, He is saying to love God more.
About selling everything - those were specific instructions to a specific man whose heart Jesus knew. Jesus knew that the ruler loved his wealth, so He challenged him. This wealth was an idol, and Jesus said to get rid of it. But what did He say? "Sell everything you have and give to the poor, and you will have treasure in heaven. Then come, follow me." He said that this was a good deed that would get him treasure in Heaven. Not entry to Heaven. Matthew renders it this way: "If you want to be perfect, go, sell your possessions and give to the poor, and you will have treasure in heaven. Then come, follow me." That was what this particular man needed to be perfect. Obviously, he fell short. Elsewhere in the New Testament, there are instructions to practice hospitality and to work to earn your living. You can't do that too well living in a cardboard box. Also, the Matthew account in particular was meant to show that one's status does not reflect God's favor. A common Jewish belief in those days was that the good people were rich, and the bad people were poor due to God's rewarding obedience on earth. However, Jesus shattered that notion in Matthew 19:23 and following. He then went on to tell the parable of the vineyard workers in chapter 20 which teaches that God is no respecter of persons (meaning, He doesn't care if you're rich, poor, black, or white).
Eating the flesh and drinking the blood is another figurative term. Jesus explained the meaning of this to His disciples at the Last Supper.
"While they were eating, Jesus took bread, gave thanks and broke it, and gave it to his disciples, saying, 'Take and eat; this is my body.' Then he took the cup, gave thanks and offered it to them, saying, 'Drink from it, all of you. This is my blood of the covenant, which is poured out for many for the forgiveness of sins.'" - Matthew 26:26-28
About being a little child: He was referring to the faith of a child. Let's look at the verse, Luke 18:17, again: "I tell you the truth, anyone who will not receive the kingdom of God like a little child will never enter it." He didn't say literally become a child. He said to receive the Kingdom of God the way a little child would. When you give a little child a good toy, he or she is going to immediately take it from you and start playing with it and enjoying it in a manner that adults have grown out of. Adults always want to repay, they don't want to accept it. Jesus doesn't want any of that, God is the Father and we are His adopted children. We can never earn this gift of eternal life that He gives us.
"For the wages of sin is death, but the gift of God is eternal life in Christ Jesus our Lord." - Romans 6:23
Being a born again infant: This guy just glossed over Jesus' response. Jesus gave an illustration that was relevant to the man He was speaking with. When you are walking around outside on a windy day, you feel the wind blow on one side, then change direction - but you can't tell where that's going to come from until it's already blowing that way. Surely an intelligent, normal adult knows this.
Anyway, Jesus explained you need to be born of the Spirit. The first birth is physical. Being born again is being born of the Spirit.
As for being more righteous than the Pharisees and teachers of the law: He is very right that there are 613 laws in the Old Testament. Then there were the hundreds of extra traditions that they added onto those, interpreting the law. However, Jesus blasted them for losing the fundamentals such as love, mercy, justice, honesty, purity, humility, and reverence. Take a look:
"Woe to you, teachers of the law and Pharisees, you hypocrites! You give a tenth of your spicesmint, dill and cummin. But you have neglected the more important matters of the lawjustice, mercy and faithfulness. You should have practiced the latter, without neglecting the former. You blind guides! You strain out a gnat but swallow a camel. Woe to you, teachers of the law and Pharisees, you hypocrites! You clean the outside of the cup and dish, but inside they are full of greed and self-indulgence. Blind Pharisee! First clean the inside of the cup and dish, and then the outside also will be clean." - Matthew 23:23-26
"On a Sabbath Jesus was teaching in one of the synagogues, and a woman was there who had been crippled by a spirit for eighteen years. She was bent over and could not straighten up at all. When Jesus saw her, he called her forward and said to her, 'Woman, you are set free from your infirmity.' Then he put his hands on her, and immediately she straightened up and praised God. Indignant because Jesus had healed on the Sabbath, the synagogue ruler said to the people, 'There are six days for work. So come and be healed on those days, not on the Sabbath.' The Lord answered him, 'You hypocrites! Doesn't each of you on the Sabbath untie his ox or donkey from the stall and lead it out to give it water? Then should not this woman, a daughter of Abraham, whom Satan has kept bound for eighteen long years, be set free on the Sabbath day from what bound her?'" - Luke 13:10-16
And he said to them: "You have a fine way of setting aside the commands of God in order to observe your own traditions! For Moses said, 'Honor your father and your mother,' and, 'Anyone who curses his father or mother must be put to death.' But you say that if a man says to his father or mother: 'Whatever help you might otherwise have received from me is Corban' (that is, a gift devoted to God), then you no longer let him do anything for his father or mother. Thus you nullify the word of God by your tradition that you have handed down. And you do many things like that." - Mark 7:9-13
Furthermore, Every lesson Jesus gives in Matthew chapters 5-7 undermines what the Pharisees taught, point by point.
So then, exceeding the righteousness of the Pharisees isn't a matter of keeping 613 laws to a T. It is having the spirit of the law and practicing it. It is having a soul that loves God and loves people. Out of that love comes your motivation for everything you say and do.
I hope you can now see the pathetic, lying claims of that video for what they are. People who devote their time to trying to debunk Christianity are some of the more pathetic people out there. If someone doesn't believe in Christianity, then shouldn't they at least be devoting their time and energy to what they do believe in. For atheists who believe in no God, and that this life is all there is, there is no reason for them to attempt to convert anyone to atheism - if this life is all there is, let people be happy. And billions of people are happy with Christianity. If Christianity is right though, we are out to save people from an afterlife of Hell. So while an atheist's motivation for converting is just being mean-spirited and intolerant, the Christian's motivation should be one of rescue. After all, if someone is sleepwalking off a cliff, the good thing to do is rescue them. For us, hell is that cliff. For the atheist, there is no cliff. Big difference there.
