I expect the above will get flagged but it's correctly pointing out that we've effectively brute forced some loopholes that allow normal protections on speech and thought to be bypassed. The fact that you "can't" say certain things ends up shifting the game to claiming your opponent has said one of those certain things.

Edit: to wit, the parent post claim in ridiculous action: https://news.ycombinator.com/item?id=34811787

Edit 2: and just to clarify my point, once these loopholes get found, people jump on them and aggressively exploit them. Look around this thread for the kinds of rhetoric people that oppose free speech are using. What would they have subbed in 15 or 50 years ago?
