Of course what's going on amongst young people at present is social contagion. This literally wasn't a thing previously, what else could it be?
And of course dysphoria is a mental illness, again what else could you call such extreme levels of mental distress about your own healthy functioning body?
And many transsexuals acknowledge this and clearly state that they know they are not the opposite sex and that they undertake risky and painful surgeries to attempt to alleviate this distress. (I dont necessarily agree with this as its imo no different from people who are distressed at not being amputees but there it is.)
TRAs and straight middle aged fetishists have created a whole new thing which is causing massive damage to women's rights, genuine transsexuals and putting children in danger.
