I'm anti-theist. Religion is bullshit. All of it. In every form. If you want to believe your life or the universe has meaning, fine--it has whatever meaning you personally ascribe to it. And tehre's nothing wrong with that. Your life is special because it's YOURS. Our world is special because it's OURS. The universe is special because we live in it. And that's a good enough 'meaning' to give it. And it doesn't require god to see things that way.
HOWEVER.
Religion isn't the root of all things wrong with the world. And doing away with it won't fix everything. It WILL, however, make people see things in a different way. Without faith to hide behind you suddenly get a very clear picture of people doing absolutely the wrong thing. Without god you have cult leaders simply commanding brainwashed followers, you have people oppressing women and homosexuals and transgender/transexual persons for absolutely no reason at all, you have creepy men marrying young teen girls, and you have people like the Pearls abusing children (and teaching other people to do it) because they are horrible people. You have abuses perpetrated for absolutely positively no reason AT ALL. Not all religion is inherently bad and not all bad people are religious, but if you take god and religion and faith away from them they suddenly lose one of the biggest crutches they have with which to defend their actions.
A world without gods won't be perfect. And if someone is inclined to want to do horrible things they will either do it with some other justification besides religion, or will do it anyway without any justification at all. Some religious people genuinely mean no harm to anyone. But again, those people would probably be nice people with or without god. The world is awesome, you're awesome, life is awesome, it's all wonderful and beautiful and special--so go out and enjoy it while you can, and make it a better place, and at the end of your life you can look back at what you did and know you were good for the sake of being good. I think that's much better than being good because your imaginary friend told you to.
