I’ve thought about this too. Being that many people in the West are christian, I’m thinking part of it is the power hierarchy in the bible (men -> women -> children).

I think part of the hate that trans women get is because people see them as men who are forfeiting their power and moving down in the hierarchy. With their understanding of the world, they are unable to understand how gender and sex are different. This leads them to thinking the actual reason for their transition is so they can go and do perverted things because they don’t understand why they would give up their power as men.

With trans men, it makes more sense to them because they are moving up in the power hierarchy. They do not think that trans men are transitioning because they are men, but because they want more power, which they see as admirable.

Why mainstream media ignores trans men I think is because they don’t view them as threats like how trans women are viewed. Wanting power is seen as a normal and admirable thing by many in the hellscape we live in and thus trans men aren’t “ragebaity” enough for the news or they just choose to focus on trans women because they are way more “ragebaity” and controversial than trans men are.
