If you look at the statistics for how many kids in a given class (of say, 35 students) identify as "trans" it will horrify you. There are anecdotal numbers out there, if you do a bit of searching.
If it were genetic, a true malady or aberration, then we shouldn't suddenly have 20% of a given class coming out as "trans". It's obviously a mania, a mass delusion, a fad, a mass psychology experiment, a psy-op, whatever you want to call it. It's peer pressure.
