> Calling somebody with his former name and mentioning his former name in a Wikipedia page are two completely different things

Except when people keep vandalizing Wikipedia renaming people there with their dead name. And yes it happens over and over and over again.

Because the most active extremists on the topic are by far the anti-trans crowd. (And it's not even close, there are trans people assaulted every week, sometimes going as far as murder this is extremism).

And again, Wikipedia keeps mentioning the former name when it's necessary (look for Bradley Manning on Wikipedia, the page redirects to Chelsea Manning but the old name is state because it's important).
