When/why/how did 4chan get so racist?

I mean 4chan being full of fucking idiots isn't anything new, but jeebus.

I think the growth in White racial awareness is not just a 4chan thing. The internet has enabled sites like Stormfront to surface which gives whites access to information and views that they could never get from the liberally biased media. On the internet, people don't have the same compulsion to adhere to political correctness and Whites are more likely to give their honest opinions, without fear of repercussions.
