Actually, I DON'T view atheists that way, nor have I EVER viewed them that way.
My own husband is a former atheist (he was an atheist when I met him), now he's agnostic, and I don't view him as being "immoral" OR a "fool" OR a tool of Satan.
Maybe you know some hypocritical Christians. I've known quite a few myself. But I strive VERY hard not to be one of them. I had sex outside of marriage before I became a Christian, but I don't now. I used to swear like a sailor, and I don't anymore. I used to drink like a sailor too. I still like having a glass of wine or two with dinner, and I had a few beers while watching the Super Bowl, but that's it. I love everyone equally, whether they're black, white, homosexual, or straight. As for homosexuals, I may not agree with their lifestyle, but that doesn't stop me from loving them. I have homosexual and bisexual friends.
By the way, I get REALLY tired of people thinking that Christians are "bigots" or "intolerant" because they disagree with a lifestyle. I think it's wrong to lie, steal, and commit adultery. Does that mean that I hate people who do those things? Of course not.
I try to be respectful of everyone, but sometimes I fail. I only have so much patience. No one is perfect.
The only difference between an atheist and a Christian is that the Christian is forgiven. Why would I look down on atheists? They've been offered the same Gift I was offered!
I have no right to look down on you, or anyone else. Christians have been instructed to love everyone as Christ loves everyone, and since it's my goal to be Christ-like, that's what I try to do.
As for the prison statistic, has it occured to you that some of them accepted Christ AFTER they got thrown in prison? Or that they say they believe in Christianity, without having any idea how to live it?
ANYONE can say they're a Christian. Well, it's one thing to talk the talk, but are they walking the walk? Obviously not, since they wound up in prison. But who knows. Maybe they really are Christians who just backslid (a LOT). Only God knows for sure.
And atheists are NOT always more tolerant. I've met some pretty intolerant atheists.
