Misandry is just a term made by men to make them look like they're victims while they are the oppressors.
Misogyny was a very common thing, and still is, while misandry is made just to make women look bad for fighting for their rights and turning the positions around. And transmen experience transandrophobia, not 'transmisandry', because misandry is a term created by cis men as a way to make themselves feel more oppressed, by claiming transmisandry exists youre saying misandry exists, because it would be a mix of transphobia and misandry, like how transmisogyny is a mix of transphobia and misogyny.
While we are at it, transmen also do not experience transmisogyny.
