ye, MRAs (men rights activists) or maby egalitarianism but the latter is just a general descriptor for social justice movements, no one really identifies just as an egalitarian
feminists sometimes claim to care about men, but it's pure larp + I completely reject their narrative about patriarchy, "toxic masculinity" etc. -- pure disinfo for the sake of blaming the victim
blackpill is purely descriptive (i.e. you know that ugly men are mistreated but you don't need to do or think anything about it) so it can't be a movement, but many blackpilled incels are effectively anti-lookist and it's the original social injustice and it mostly affects men, so ye
identifying as incel suggests being anti-lookist but it's not necessarily true + a non-incel could be an ally in theory (in theory cos people aren't gonna give up their privileges ever, only fake social justice movements have allies)
