no it isn't
religion is just like communism, it works in theory but mankind fucks it up, and everyone always reports and remembers the bad parts of any religions history, but they tend to forget the immeasurable positive impact it has had on anything around it, but go ahead and let a few bad apples ruin the whole bunch
and dj is right about religion not being able to be a private thing, same thing as with seperation of church and state, it isn't supposed to keep religion out of politics, it is supposed to keep the gov from sponsoring a church for a national religion, but you cannot keep religion out of the way our politicians decide on issues and who we vote for because of their morals
