As far as I recall, MN used to ban people (or possibly delete posts) that referred to trans identified males, not sure what the rules are now.
Still in the guidelines, and afaik subject to the possibility of 3 deletes getting a suspension, in the section which covers 'misgendering'.
That said, it’s clear that most trans people find the use of pronouns or names that they or others have consciously rejected, to be hurtful and would therefore struggle to engage in a discussion with those who insist on using them. The same is true of the expression ‘Trans-Identified Male’ or ‘TIM’. Likewise, many feminists are affronted by the term ‘cis’ and ‘terf’, so using these terms will make civil debate less likely. As we’ve said, context is everything – but our moderation team will most likely delete these expressions if we feel they're being used in a deliberately inflammatory way.
The problem is this 'context' thing. There are plenty of discussions around the use of 'TERF' or 'cis', but using 'TIM' - even in a way most of us wouldn't think was inflammatory or directed at a specific individual - is liable to get deleted. I don't believe this post will as it's very clearly just discussing guidelines and usage - if anyone reports it that would say a lot about them.
