it is very true that some transman don’t take offense or even rather be more feminine, even while being a man. i repeat, even as they are a MAN, because ones clothing does not dictate their gender. However, if you only think of transmen in that way, then you are not being inclusive to those who feel that way, you are being transphobic.
i could write a whole essay in this, but i would rather stay on the topic of Regulus Black. It has come to my attention that whenever Regulus is dictated as trans, he is often referred to as small, petite, witty, sarcastic, and with no sense of humor, while James (or whoever he is shipped with) is the complete opposite. I also find it ironic how, despite being a trans MAN, in no fic Regulus appears with bottom surgery, only top surgery. It really may be just my impression, since the amount of fetishisation and misogyny in this fandom is news to no one. But if you think of every trans man as a “helpless bottom twink” than block me.
