Some of the double standards I've noticed among trans people:
When a transfem makes posts about how you can "you should start estrogen", it's treated like detransition rhetoric, and she's demanded to put lengthy disclaimers to prevent her from upsetting AFAB readers
When a transmasc talks about the "miracle of testosterone" or recommending you start it, it's fine.
When a trans social group has mostly trans women, it's a bad sign, and they need to represent transmascs more ASAP
When a trans advocate group is led by mostly trans men, it's just an unfortunate result of random chance
Calling a transmasc whiny is hard misgendering, as only women can be whiny. Calling a trans woman a bro or dude is fine, though. As is directly stating her feminist leanings are due to a mental illness
When a transmasc runs into a transfem kink post by accident, it's the transfems fault and she's treated as on par with sexual predators
When a transmasc directly tells a transfem that she should kiss or even have sex with him instead of arguing, it's funny
Pointing out the objective fact transmasc spaces have a misogyny problem is bioessentialism.
Saying that T makes you a strong man and E will dissolve your muscles is not.
When a transfem distrusts men due to a lifetime of abuse, it's considered a symptom of a disease at best, and can only be stopped through forcing interactions with men.
When a transmasc directly says "I can't relate to women because I'm transmasc and have dysphoria" it's just how people work and you can't force him to do anything.
Telling a transmasc he benefits from male privileged at all is considered a grievous insult, and a denial of every problem he has
Transfems must be reminded of every bit of privilege they get at every possible moment, including lack of periods or pregnancy.
This is not even close to the full list of double standards. People often mockingly ask how male privilege is supposed to help trans people. It's hard to answer, not because they epic owned me, but because expecting a single solid ubiquitous answer ignores that privilege is not that easy to point at. It's a lot of small things, each one appearing minor but building up to something that can't possible be denied... except by those that benefit from it.
