Do you incorporate faith/religion in the Sims?

Sometimes I make families more conservative than others, but I do wish EA would make up some religions for sims to follow, not IRL ones because that could raise controversy, but I NEED sims to be able to FIGHT with their parents because In sims its not normal to get in fights but I NEED that to make myself satisfied with my sims lives, more realistic relationships. Like if a child wanted to rebel from a strictly religious family etc.
