First of all, you're mistaking religion for the people who claim to follow it. Just because a person claims to be a Christian doesn't mean you should take what they do and apply it to the religion. (And the Bible appears to agree with this, it states that 140,000[Or 110,000; I can't remember offhand] of the Tribes of Judah will go to heaven, and we have millions of Christians). The oppressive things Christians do(Banning gay marriage, things like that) are wrong. I believe God gave man the choice to follow Him or not, and going in after Him and attempting to force people to be Godlike is a major overstepping of boundaries. (Even Hell is an example of God's love, it's not a punishment, if you go there you've shown you don't want a relationship with God, and God allows you to go to the only place outside of God's jurisdiction, where you will never have to worry about Him again). The trick is to listen to God, not those who say they're speaking for Him, because they will lead you astray. I don't even go to Church anymore, and I won't unless I find a church that suits my beliefs. Once I realized how violently stupid the Christians I saw everywhere were, I realized I'd have to pursue salvation on my own, and my relationship with God has never been better. Before when I prayed, I didn't feel any better about myself afterward, now there's a tangible sensation(I can't describe it, it's like I'm losing ten pounds in an instant) when I ask forgiveness. I still have problems, but I've come closer than ever to solving them.
What I'm basically saying is, religion is not responsible for 3/4 of the world's problems, people who say they follow those religions are.
Also, what's wrong with Muslims' wanting to remove pictures of Mohammad from Wikipedia? Atheists have done the same thing with prayer in school, seeking the removal of something that was against their beliefs, and they got what they wanted.
