The entire schtick of 4chan is lying, bullshitting and insulting others for fun, for kicks even if it didn't start out that way in the first place. Even when 4chan tries to have legitimate discussions someone will post niggerfaggot or something hyperbolic and stupid to shit the place up. Reddit on the other hand is more akin to a blogging website with a mob mentality, mobs always right, never deviate from the hive mind. No legitimate discussions happen on reddit, it's all narrative control. So when you do try to deviate from the hive mind you get whacked. 4chan represents actual diversity of thought and agglomerate opinions, even if it's communities are very spastic and separate nowdays while reddit is just a bunch of yes men soyjacks, vapid women and fetishistic troons.
