Yeah, it's of course legitimate to argue against some specific tool or strategy to combat harassment, like the changes proposed here.

But your post sounded as if the whole concept of "harassment" was problematic, due to the risk of people abusing the anti-harrasment tools for censorship. I agree, the risk is there and needs to adressed, but situations of real harassment and "mob dynamics", in which an individual user suffers real harm but can't do anything about it themselves, also happen frequently. I think it's dangerous to ignore those by throwing the whole concept under the bus.
