“Trans men are just men, but all women are property of men, therefore trans women are sneaky, deceitful predators trying to trick both innocent men and women.”
This is all just an extension of our fucked up patriarchal culture. It’s not that trans men are forgotten, it’s that their outward masculinity makes them irrelevant. They are no longer potential mates for the cishet males and therefore not “dangerous.”
Trans women, however, are a “problem” for those same reasons. Their femininity means they could be targeted as a potential mate for a cishet male, so to the patriarchal privileged they are by nature of existing “deceptive, duplicitous queers.” At the same time, any remaining masculinity in appearance or even the idea that a person could have a penis makes them a threat to other women, because other women are the property of other men. Hence the “trans women are just rapist men using drag to trap women in bathrooms” fallacy that the right loves so much.
I apologize for the window into that psychology. A shower may be warranted.
