Asians, a hundred percent. They have little sexual dimorphism because they have little sexual expression (small breasts, small penis, little body hair, little difference in height/frame/musculature). There's a reason thai trannies are the only ones that pass and it's not just plastic surgery and makeup, they're all a blank canvas from the start because they barely develop male features. Asians are like scaled up children -- which probably has something to do with their propensity for pedophilia, and the overlap if weeaboos and pedophiles.
This has interesting implications because sexual dimorphism is a hallmark of tournament species, whereas the absence of it is the hallmark of a pair bonding species. Tournament species have an unbalanced ratio of sexes, have high intrasexual competition and thus high incidence of violence, are nonmonogamous as dominant males breed with multiple partners, males don't take part in raising offspring -- basically, niggers. Pair bonding species are the opposite, with low intrasexual competition, low rates of violence, monogamy, and coparenting. The running hypothesis in human behavioral biology is that humans are in the process of evolving from a tournament species to a pair bonding species; which, if true, would mean the bugman is unfortunately the next step in human evolution, and the nips and gooks are on the bleeding edge, and we should be paying attention and taking note of the pitfalls that are destroying their birthrate and causing their extinction.
Natives. They're all round on top, sticks on the bottom, long haired and drunk/high. Like you stand a row of them facing away from you and you'll never tell which are women and which are men. They'll all just look like indistinct blob shaped people-like things.
Fat people don't count, being fat wreaks havoc on the endocrine system and practically turns you intersex, that's why genderblobs are genderblobs.
It's true you don't see many abbo women. And in fact, they are so alike in voice and appearance, that they are often mistaken for abbo men. And this in turn has given rise to the belief that there are no abbo women, and that abbos just spring out of holes in the ground!
