I realize you are talking about people on NS, but that is a wide miscalculation of the whole population.
I would say a small percentage of atheists "loudly preach" (btw not the best word choice when talking about atheists). If I had to guess, around 30-40% (about all the atheists who partake in internet forum discussion) while just about 70-80% of theists blazon their religion. Think, atheists don't have churches that proclaim on signs "JOIN US". Atheists don't go around to middle/elementary schools and protest about how religion is murder. There is about 1 atheist tv program and about 1-2 religious programs for every state. You say atheists are "idiotic at best" because they criticize other people, smfh you just maligned all atheists. Can someone get more hypocritical.
