That is an insane thing to say. Qanon level insanity. Trans activism is big pharma selling HRT to kids? First off, HRT is expensive, but not that expensive. Whatever made up narrative you have for them convincing kids to support trans people would be entirely too expensive to justify. Second, trans people have existed for MUCH MUCH longer than pharmaceutical companies have existed.
