That's what I like about 4chan. In a sea of ungodly acidic garbage lies a golden heart of contrarianism. The posters will argue for a side one day, and 2 hours later will vehemently adopt opposite arguments. Some of the best leftist arguments I have ever read came from /pol/.
4chan argues for the sake of arguing, and I think that is absolutely beautiful in today's environment of everyone taking everything so seriously.
