Blackpill will never be mainstream to begin with, because although certain social groups do get a pass for not being able to succeed in certain situations and aspects of life, for men it will always be a bootstraps first mentality.
This is because, while women do have an influence on the way men behave (see: SIMP Economy, Women are Wonderful, etc.), other men, in an attempt to gain some female validation, will always enforce a standard on men who don't think that way.
All of this is not even a political issue too. Just look at MGTOW and hyper traditionalist channels gasping at the modern women but are willing to do anything and die in a useless war for a women who decides to be traditional or the male feminist self-hate channels.
