I'm gonna be honest, I've never watched these manosphere losers, but there are enough "no manlets" or "nobody under 6ft" ass women out there (mostly on dating sites, unfortunately which have become the primary way people meet partners these days) that the manosphere doesn't need to try hard to sell that one, women sell it themselves like an updated version of men wearing "no fat chicks" shirts in the 80s. Never seen "only short guys" or "nobody over 6ft" either, in contrast. There's "chubby chasers," where my "shorty seekers" at?
I know there are women out there that do date short guys and one shouldn't let the demoralizing messages from what I'm sure are horrible people anyway get to them, but ask a girl who was fat in the 80s, it isn't fun to see even though there are guys who are fine with fat chicks.
