They are against God. How can you trust people with no God.
How can you trust people with a god? They act not out of morals, but out of fear of eternal torture. Do what I say, OR BURN!
I trust the atheist - he is good because he is good.
So, you have a religion of ripping people off by trying to get them to think that atheists are good.
As an Atheist you wouldn't have any external incentive to be good. You have ''incentives'' to not be bad, which is the law and the fact that you can get punished for it. When it comes to doing good, though, you aren't good just because god tells you or because you want to go to heaven, you are good because you are, which is far better.
