It sounds like you are blindly putting a lot of trust in what people have told you. People, even church people, can be mistaken. What does the Bible say?
About dancing:
Exodus 15:20 And Miriam the prophetess, the sister of Aaron, took a timbrel in her hand; and all the women went out after her with timbrels and with dances.
2 Samuel 6:14 And David danced before the Lord with all his might; and David was girded with a linen ephod.
Psalm 149:3 Let them praise his name in the dance: let them sing praises unto him with the timbrel and harp.
Psalm 150:4 Praise him with the timbrel and dance: praise him with stringed instruments and organs.
Jeremiah 31:13 Then shall the virgin rejoice in the dance, both young men and old together: for I will turn their mourning into joy, and will comfort them, and make them rejoice from their sorrow.
About Jesus (and about other people's opinions):
Matthew 11:16-19 But whereunto shall I liken this generation? It is like unto children sitting in the markets, and calling unto their fellows, And saying, We have piped unto you, and ye have not danced; we have mourned unto you, and ye have not lamented. For John came neither eating nor drinking, and they say, He hath a devil. The Son of man came eating and drinking, and they say, Behold a man gluttonous, and a winebibber, a friend of publicans and sinners. But wisdom is justified of her children.
About being joyful:
Galations 5:22-23 But the fruit of the Spirit is love, joy, peace, longsuffering, gentleness, goodness, faith, Meekness, temperance: against such there is no law.
About women:
Genesis 1:27 So God created man in his own image, in the image of God created he him; male and female created he them.
Genesis 5:2 Male and female created he them; and blessed them, and called their name Adam, in the day when they were created.
About divorce:
Matthew 5:32 But I say unto you, That whosoever shall put away his wife, saving for the cause of fornication, causeth her to commit adultery: and whosoever shall marry her that is divorced committeth adultery.
About forgiveness:
John 8:3-11 And the scribes and Pharisees brought unto him a woman taken in adultery; and when they had set her in the midst, They say unto him, Master, this woman was taken in adultery, in the very act. Now Moses in the law commanded us, that such should be stoned: but what sayest thou? This they said, tempting him, that they might have to accuse him. But Jesus stooped down, and with his finger wrote on the ground, as though he heard them not. So when they continued asking him, he lifted up himself, and said unto them, He that is without sin among you, let him first cast a stone at her. And again he stooped down, and wrote on the ground. And they which heard it, being convicted by their own conscience, went out one by one, beginning at the eldest, even unto the last: and Jesus was left alone, and the woman standing in the midst. When Jesus had lifted up himself, and saw none but the woman, he said unto her, Woman, where are those thine accusers? hath no man condemned thee? She said, No man, Lord. And Jesus said unto her, Neither do I condemn thee: go, and sin no more.
But go to this thing with this understanding.... if these Jewish people are practicing, then throw out any idea that they don't love the same God you do. Perhaps they don't have an understanding of messiah that we do (that he has come) but they await him as do we... we just know it as his return. My point is, they are not going to do anything that will profane the name (character, reputation, authority) of God.
