I have a grudge against organized religion because of personal experience and the egregious misdirection of power it often employs. There is a lot of potential for good there, but it often goes unnoticed by the figureheads and instead becomes a detriment to progress.
And then there's the fact that many of the thinkers here find that religious zealotry is a dead-end in discussing something and sharing ideas.
My 15-year experience with Catholicism showed me that the Church can do a lot of good, but at the end of the day I didn't believe a word of it sincerely and what became my future dislike of organized religion was exacerbated by several Jesus-freak relatives trying to bring me "back into the light" and being forced to be confirmed and attend mass for over a year on pain of eviction from my house, which is inhabited by my parents who are generally very nice people but suddenly weren't when religion was put into the equation. I don't know what it is about religion that would make parents threaten their straight-A student, non-problem, respectful kid with being thrown out of the house, but it's the same kind of thing which has caused me to embrace this "Hate Religion" mentality Phil mentioned in the original post. What pisses me off is the "Love Religion" mentality which makes people narrow-minded enough to not respect the beliefs of others. Mind you, this doesn't apply to most religious people, because most people are very respectful of alternative beliefs, but that about covers it, I think.
I would hate to have to deal with parents like that. My mother is a devout Catholic, but she refused to fascistly force her beliefs on me.
In fact, the only time that I've ever been to Church was when I was a pall-bearer at my great-aunt's funeral. Until then, I wasn't even aware that everyone else in my family is Catholic.
These days, I'm more grateful than ever to be afforded the freedom to not be Catholic.
