When I was younger, my dad used to shave until his skin bled, mostly because he has extremely thick facial hair (that I inherited) and he needs to press hard and repeatedly to shave even half of it off. This plus starving himself and generally being soy.
No. I think it’s stupid and just a meme that people take seriously for some reason. Scientists have done a decent amount of studies on it, and there’s no real evidence for a “tranny gene” no matter how much anecdotal evidence there is of 4tranners describing their parents as “obvious reppers”
