Why do we keep being encouraged to believe that the hate speech of neo-nazis is worth preserving?
The social justice movement in the U.S. for example is so successful, because they exploit this. They're failures at life that label everything that makes others more successful than them hateful to get it changed.
Let me respectfully suggest that your original comment was poorly worded, given your stated intent here.
Best.
The reason we have been tolerating neo-nazis for so long is that we've established a principle called free speech, and we've developed a legal theory and a society where Trump cannot use his power to turn the tables and ban discussion of things he finds objectionable: perhaps he'd like to institute a ban on discussing racial justice because he finds it "hateful" and divisive? Perhaps he (or someone in his administration) would like to ban the hateful, hateful folks who advocate legalizing what he would call the murder of unborn children?
Now is the exact moment you should be on your knees thanking all of those assholes who defended the freedom of speech of the neo nazis of every time period against governments who acted with the best intentions, trying to stop hate. Because the hateful ones are now the ones who get to decide what 'hateful' means.
As for Trump, $10 says you're in for a big surprise.
