Why are you insisting they're inventing harms? Do you have evidence to support this? Are you just opposed to the idea of ethics?
I have a creepy feeling that this entire thread has been infested by Facebook insiders who are working on something that is awful, and lobbied and heckled to get the people fired who were telling them it was awful. No one else would have this sort of venom.
How about we just don't mock people?
Mockery is a very powerful tool to speak truth to power.
