as a trans man (not the person who sent the original anon) I think part of the nuance needed is that as trans men we're also victims of the same patriarchy that hurts women and have been victims of the double standard that you talked about. so it's really hard to reconcile that when also being told that because you are a man you are a misogynist. even though as trans men, we live through and are harmed by the same misogyny that hurts women. it hurts being told that "trans men on the side of the oppressor" or that "trans men are misogynistic because they are men" not only because it is transphobic, but also because it completely invalidates any struggles with misogyny we have faced or continue to face.
I am not sure which previous anon you are referring to. But as someone who's genderqueer masc, I understand what you mean. Being trans is a double edged sword at times. You are literally walking on a tightrope when it comes to gender identity and society's understanding of what your gender identity even is.
Often times that can also mean that people assume we have it easy. The problem with trauma is that we all have the unfortunate tendency of comparing it with each other. Trans men CAN be misogynistic. (Sad but true, and one should always try to correct their behaviour when they're called on it) AND they can face misogyny pre-transition or post-transition. (If they wish to transition)
It is important to not downplay someone's experiences just to portray yours as worse. And THAT particular advice applies to EVERYONE. The advice is gender neutral
