Why are atheists so deluded?

We aren't 100% sure. There is just more physical and tangible evidence supporting the No God Theory then there is for a God existing. And we are generally angry because we get attacked. They did a study at a college in Minnesota in 2006 and found out that atheists are trusted less then gays, s, and muslims. Now, think about how controversial these groups have been in the media lately. Ya, that's why we are angry. I will give it to you though, many atheists are quite elitist.
