According  to Silas (member of yahoo answers)

Most of the atheists that I have heard or seen think that people that believe in any religion (Christianity for the most part) are idiots, bad people, or crazy. Now I'm sure there are atheists that don't think this way but I haven't seen or heard from one that doesn't. I am a Christian but have no problem with people who are gay,atheist, or from a different religion. From what I've experienced atheists think that religion is a social issue and believe that religion is the cause of war,violence, and such. When most religions are against such things. I just want to know why atheists have to think this way and why cant all people just live to respect each other and why atheists believe that the sooner religion is gone the better.
