It actually is, you have to trust the market to call out the speech that is vile. Vile is relative though, and the standards change. SA is having a hard time pulling through some of this. What was accepable filth is now getting cross-checked once and a while.What a twisted and myopic notion of "free speech." Vulgar language and denigrating others is not free speech, it is crass and uncivil. Free speech is not license to be rude, misogynistic, or racist.
SBO moderators do a great job here, but its a free forum for entertainment purposes only. I wouldnt whine if objectionable material got missed.
