So philosophically a 48yo, 6ft4 and 200lbs man can be taken as a 5ft4 90lbs woman. That means if I repeat "Charmander" enough times, it will socially construct itself in this reality.
What you're saying is “Fat, ugly, flat-chested, etc. women are not real women, I only care about my kind of true women, please only show me these”. That's exactly what I was talking about. The measure to define women in your head is shaped like that, and you reluctantly decide to let someone pass. Yes, it is common. Yes, it is stupid. What's actually new in that?
