I think the official story is not that he committed suicide but that he accidentally poisoned himself in the course of research, and the suicide story has just sort of been perpetuated in pop culture as a “tragic gays” narrative to make his death romantic (in the broader sense of the word).

I’ve never seen reason to believe he was murdered, though I’m not saying you’re wrong.

Philosophy has a tendency to need to use very specialized language to avoid problems of ambiguity and to precisely identify concepts that have no reason to come up in the vast, vast majority of conversation among laypeople.

The rules lean towards “civility” over the actual content of what is said, which left it vulnerable to “just asking questions” types. It’s being revised after a spat with a TERF who took advantage of those rules.
