Why don't you mind racist shit against black people in forums and 4Chan? Do you think black people shouldn't mind it either? Where else do you think racism is acceptable?
The alternative is freedom of choice. Right-wingers will always whine that there’s no freedom of speech when liberals aren’t forced to listen to their drivel. Welcome to the marketplace of ideas!
Taken at face value, I find this forum is far more unpleasant, and far less inclusive, than a bunch of high school nerds trying to shock each other with naughty words. They're not trying to outsmart each other for fake internet points.
