I imagine a town where believers and nonbelievers, christians, atheists, pagans, heterosexuals and homosexuals all live together happily and without arguments or fighting where everyone accepts and loves each other.
Is it possible? Why or why not?
I doubt they could live together without at least disagreeing.
I'm a Christian. So in this paradisic world you envision, would Christian preachers be forced to perform gay "marriages"? Would Christian doctor's be forced to provide abortion on demand? Would Hobby Lobby be forced to provide the "day after" birth control (which is really killing a living person)?
I really don't mean to start an argument with you or anybody else by asking these questions...but they help me answer your OP. I'll explain more further down.
These types of questions (referring back to your OP now) always remind me of the following quotes from Star Wars.
1) From episode II:
Anakin: "We need a system where the politicians sit down and discuss the problem. Agree what's in the best interests of all the people, and do it."
Padme: "That's exactly what they do, the trouble is that people don't always agree."
Anakin: "Then they should be made to."
Padme: "By whom? Who's going to make them?"
Anakin: "I don't know. Someone."
Padme: "You?"
Anakin: "Of course not me!"
Padme: "Then someone...?"
Anakin: "Someone wise."
Padme: "That sounds an awful lot like a dictatorship to me."
Anakin: "Well... if it works..."
2) From episode 3:
Darth Sidious (future evil Emperor): “Once more the Sith will rule the galaxy! And...we shall have...
peace.”
Notice that what seems like "peace" to the future emperor really just means everybody doing things the way
he wants them to be done.
So again, I wasn't trying to cause an argument above, but only asking those questions to get to a point, which is that I don't think we can have a world in which there is no disagreement because man is a fallen creature and he would rather do things his way than God's way. That was the whole point of what happened in Eden. Man decided to be his own authority regarding objective moral values and duties. It is only when we all submit to the one who truly is the authority regarding objective moral values and duties that we will have peace. Can this be accomplished on earth? Not yet.
