It is probably really hard for you to separe the christian values of your society from what you learned from other cultures. The fact is, even if you are not a practicing christian, I know I am not, western religion is ingrained in society's values and ethical morals. If you were to be able to magically remove all influence any Religion had in any one's life, you'd take the good and the bad, and you'd see absolutely nothing, because our culture's beliefs are completely fused down to the core of who we are.
I do not believe in god, but I do believe in the power that Religion has to control and guide the masses, be it in a good way or a bad way. Religion is a powerful tool to understand where and who we are as individuals. Abolishing a right to believe is just as bad as abolishing a right to not.
