It's also why they desperately cling to anime pfps and Felix the cat boy or Ruka from Steins Gate rather than anything that actually represents them accurately. It breaks the illusion that they're all heckin valid gorls if you have to look at their actual mugs lmfao. Like, this picture really highlights why they need to cling to cutesy aesthetics to claim any semblance of being women:

Otherwise they're too blatantly male with whole ass male bodies (however altered by mutilation or hormones), male interests, male hobbies, male mindsets, etc. At least with the veneer of a cutesy anime aesthetic they can be plausibly "women".
