It makes sense to feel pissed if someone you’re experiencing gender envy towards explicitly doesn’t want to present that way, because it can feel like you’re sort of being disrespected by proxy because they’re not respecting the thing you covet so much. But the thing is that everyone is different and something so essential and desired for you can literally just be repulsive and undesirable for someone else. It’s like different kinds of candy. It’s normal to be kind of angry if someone has licorice and you like licorice, but they throw it away because they don’t like licorice. But, not only would you never force someone to eat licorice, gender expression isn’t a discrete thing that can be transferred like licorice is! So our reactions are something we shouldn’t beat ourselves up over, but we also don’t want to let it make us hurt or affect our actual opinion of our trans comrades (and it should go without saying that this applies both directions for transmasc and transfemme people!).
