Given the rules specifically refer to "targeted" misgendering and deadnaming, I don't see how your concerns about "keeping up" are applicable. Seems clear to me how it works: Don't seek out some person on twitter and deliberately harass them with the gender they aren't and the name they don't have. Aside, lots of people in this thread appear to be reacting like this is a very complicated rule, but this doesn't seem like something that needs to be carefully interpreted against the standing fabric of society.

Toward your comment, can't we establish harm is caused by targeted misgendering/deadnaming by asking the transgender people who have been harassed by it how they feel about it? Doesn't that seem not even necessary? What line on harm needs to be drawn exactly before we can make a rule "don't deliberately harass transgender people on our platform via their dead identities."
