Weren't you saying about people being programmable? Every society throughout history has struggled with administering justice equally. Every single one.
The reality is both ends of the spectrum are undesirable. To move too far in either direction ends in murder and destruction.
You can google that sentence, you can read defenses of it and make up your mind. I'm not that passionate about changing a single opinion that I'm going to waste time chasing after your ever expanding requirements.
I had never heard of the term but I would certainly agree that it's hate speech. It seems to me that it was a twitter hashtag that some people thought was funny.
I don't agree with it but I also think that an equivalent hashtag #killallwomen would have an equally hard time being brought before a judge.
I find it rude to simply turn around and walk away without saying why I chose to. I remembered previous conversations I had that went the same way and ended in me being dragged along and my time being wasted. Fool me once, shame on me etc etc. I apologize if that was not your intention.
But some level of social cohesion is desirable, and I think starting at the level of 'not allowed to advocate for the rape and murder of peoples' is a reasonable step towards ensuring less people think that is viable.
