I understand this. I think what kind of annoyed me the most is
Just as it's racist to believe that black people are inherently less intelligent, even if you don't necessarily hate them, it's transphobic to believe that a trans person's identity is worth less or is less valid that a cis person's, even if you don't feel any malice for trans people.
I don't really think it's fair equivalence to make. I think it would be transphobic to claim someone is less intelligent or should be penalised in society, although I am probably approaching this with a philosophical/theological view rather than how people should be treated.
I don't really like the idea of being told how to think about things. I think this is a slight step too far, if it means forcing someone to agree with something they're not comfortable with agreeing with.
I'd rather if there was a more clear-cut "this is a controversial issue - please don't talk about it". I wouldn't expect a transgender person to have to care about anyone else's moral convictions except their own. As long as they're treated equally. So I think I can moreso accept a "please don't talk about it" as I think any such discussion about "what is a man/woman" isn't actually a productive way of looking at things.
Because moreso what concerns me isn't if people should be given gender affirming care, but at what stage is it appropriate and who should pay for it.
Another thing I don't really like about it:
For a more in depth look at the question, and why anti-trans activists are wrong about it, see the Lonerbox video "What Is A Woman?" A Response to Matt Walsh. (Fair warning contains a lot of Twitter lefty shitposter jokes/language).
Is this really unbiased if it's what "Twitter lefty shitposter"s think? I've found that group to be pretty toxic and malicious, and chosen to avoid that crowd.
But apart from that, the guidelines are quite clear on how to act on the instance. I just wish there was more dialogue about the issue.
