The feeling of body dysphoria cannot be ignored , its causes are very unclear
One problem with this is that - as often described in FWR - a high proportion of girls develop body dysphoria during puberty. I did: I took up cutting and became anorexic, which I now see as a (partially successful) attempt to not become a woman. It's not unusual for boys, either - becoming a man's a fairly heavy burden. My brother decided to be gay for 4 years.
I can't tell you how what I experienced, or my brother, compares to the dysphoria felt by trans people. Neither can you. All we have are subjective descriptions - and symptoms, which are mostly the same.
So we still don't even know what it is, let alone what to do about it. I wish we'd start by ignoring gender. That ain't happening any time soon, though, and it makes me nervous when people assume the best response to gender discomfort is to alter the body.
