Good to see the Valley is starting to get off its "we are just a platform, all information should be free and neutral no matter how bad, so we're not responsible" extremism of the past few years and understand that some forms of speech are harmful should not ever be encouraged and accelerated on any platform or technology, ever. To the people that say "Where does it end?" – that's pretty easy. Let's start with curbin…
The next would be maybe an argument of banning speech that _indirectly_ calls for physical harm, since that leaves room for interpretation. Calling for a white ethno-state indirectly calls for physical harm to all non-whites. Why? Because how the hell else are you going to move us out, other than by force? Are you planning to pay each of us $2 million to leave the country? Obviously not.
The third would be all other forms of hate speech (which arguably would cause even more debate).
