I mean you say they’re well defined but your own explanation is a vague generalization. I don’t think any decent & rational person wants to deprive trans people of basic human rights, but that doesn’t mean they’re comfortable with every single demand of activists either, which is probably the actual intent of the message.

As for the “no nazi bullshit” part, this doesn’t tell me anything except that the community has some childish and unstable people who have a habit of calling everyone they disagree with a nazi. It’s not hard to be “worried that that includes you” when there are plenty of people who would call someone a nazi for just about anything or for being even slightly to the right of them on any issue.

It has very little to do with a literal interpretation of these words, which these types always hide behind because they are cowards, and everything to do with the implicit meaning given broader context.
