What's funny about many religions is that they have many common good traits and if only religious leaders focused on these instead of smaller differences, I believe everyone could coexist better.
The problem is that most religious texts conflict with other religious texts, and the "true believers" in a religion as an actual religion and not a set of principles by which to abide see others as claiming
their religious text is the truth which is indirectly claiming that your religious text is false.
I see no problem with religion if it is the framework by which people are taught morals. I only object to religions with morally wrong content - such as the treatment of women promoted by Muslims. Even then, the person in question who believes that might not believe every part of it, and might reject the parts of it that
are terrible. By acknowledging that I can accept that someone might believe in the core beliefs of a religion I think is abhorrent, but may not be a bad person themselves. It's all about personal beliefs, and it's often easier to say "I'm Christian" than describe every part of what you believe. It's like a musical genre - it's all about categorization.
The Vatican can go forget themselves, though.
