not caring about someone's feelings is pretty important when you're talking about things that exclusively involve people's feelings. i don't think you really mean that though
i mostly meant people saying "it's all in your head" as if that means it's easy to cope with something on your own. a mental illness is by definition something that excessively burdens you to the point where it's disruptive to living, and gender dysphoria fits the bill on that.
reassignment surgery is a treatment. it sounds extreme and it's certainly not something most people (and probably a fair number of trans people) wouldn't want to do, but if someone's dysphoria is extreme enough, that might be what they have to do to actually feel happy in their own skin. but i think (no source on this, just intuition) most trans people don't actually do it anyway
i'm not sure what the last reply means in the context but i'm guessing you're just dismissing stuff again
I wouldn't go that far but I get what you're saying
yeah mostly just meant that there are a lot more people who either are depressed or know someone who is compared to people who are trans or know someone who is trans. a generous rounding-up would put ~7 out of 100 americans as depressed, and only ~1 out of 100 americans as trans
