It's far lesser to the "fucking bigots" reasons, but I also hate the transphobic obsession with "biology" for the way it flattens actual biological knowledge of our species to a stupid cartoon version of the subject. Human genetics is *fascinating* but ppl just want enough facts to be assholes with.

Chromosomes as a whole, your karyotype, is like the 100,000 foot view of what your genes are doing. There's also the lower level sequence changes, some of which exist in different versions in our populations. And there's epigenetics-kind of like, which genes get turned on or not. And and and

they don't even care if they're facts!
