There's a huge range between the ad hoc and the binary. For example, I think Mill's Harm Principle is a good place to start.

I guess that's my point: I don't think it's a useful heuristic at all. Imo, the great majority of people worried about trans jokes and not Irish jokes are primarily on the political left, which makes it a political issue. But it should be (and in fact is) a moral issue: is X being harmed by Y? If so, we ought to punish Y.
