Someone who doesn't believe in any God. There are two types.
1. The live and let live atheists who don't shove their opinions down any ones throat. These people have social lives.
2. The arrogant, intolerant pricks who send all day long bitching and trolling on the youtube comments sections. They always talk about reason and logic but lack the logic to realize that no one is being persuaded by their intolerance. They are postive that there is no afterlife yet they spend that only life on the interent trolling people. Most of them are 15 year olds who think that they are really cool even though they don't have any friends.
Even the average Catholic priest gets more ass than the average militant atheist.
" The bigotry of the nonbeliever is for me nearly as funny as the bigotry of the believer. " -Albert Einstien
Militant Atheist: I'am atheist therefore that makes me smarter and better than everone else and I show that by trolling people on youtube.
Smart person: How about , you get a fucking life.
