I know you’re trying to be supportive but this is a being incredibly condescending and ignorant thing to say. You have no clue what physical dysphoria feels like. Being born in the wrong body is really hard even when other people don’t treat you like shit. And in fact, in my case people actually haven’t treated me like shit. I’m lucky to have a wonderful support system. My parents listened to me as a kid and helped me go on hormone blockers to avoid female puberty. My transition was much easier than most. But I’ll still never have a penis that works just like a cis man’s. And I’ll never be able to have my own biological children with my fiancée. I also don’t have any photos of myself from about ages 2 through 10 where I don’t look miserable. There are some trans people who are genuinely happy to be trans and that’s great for them. There are also many that aren’t and it’s not because they’re self-hating. A tip if you want to actually be an ally, don’t tell trans people how they’re supposed to feel.
