But let's go /pol/ for a hot sec. Oh hey! Ctrl-F says there's 5 occurrences of the n-word (Hard -r too!).
I'm not black, but I imagine that just ignoring stuff like that really gets to you after awhile. Here is a forum where people actively demean others based on the color of their skin, and not only is it normal, but if you're going to visit you need to make sure no one knows that they're actually black. So should they just pretend to be white?
I am simply saying that if you're black, you're affected by the discourse on 4chan much differently than you would be if you are white. A few black nationalists is a lot different than the sea of n-word use, and it affects folks much, much differently.
There was also that Shia LeBouf incident, where black and hispanic members of /pol/ from NYC showed up to disrupt his political performance art thing he was live streaming. These people exist, contrary to our political assumptions, the world is a stange place.
