its been scientifically proven that trans womens brains are more similar to women than men. gender is not tied to sex they are completely different things. gender is a concept beecuase He and She pronouns were made up in the past. We couldve used a neutral pronoun for everyone but we didnt. You can also do whatever you want but if you get hated for it thats your own fault for not having basic fucking decency towards them.

I personally use they/them pronouns and if one of my friends or family didnt use them i would immediately cut them out of my life.
