It is the whole tumblr psychotic mindset. Troons don't try to pass, because trying to look like a women would mean they weren't women in the first place. Girldicks, girlstubble, girladamsapples, those are a natural part of the female anatomy you fucking shitlord. It's normal for women to be balding and 6'3" with a visible erection.
Traps, on the other hand, understand that they have a massive disadvantage to natural born women when it comes to looking like a hot lady, and work hard on their physique, clothes, hair, and makeup.
A huge percentage of the batshit troons that are so popular on the Farms aren't legitimate MTF transgender, but deeply unhappy people who believe getting their dicks cut off will cure their depression, social anxiety, and self-loathing. The end result is people who weren't able to maintain their appearance, or even basic hygiene, pre-transition suddenly finding a whole new world of clothes, makeup, and grooming which they are completely unprepared for.
