Because although its not 100% misogynistic, it does have plenty of misogyny at its core.
And misogyny is a right wing/conservative attribute to begin with. You aren't going to be able to separate them or keep this manosphere shyt from having overlap with white supremacy no matter what you do unless you can get the misogyny out of the mix. And I don't think that's likely.
I think at this point the whole "fukk these bytches" stuff is core to the black manosphere. So if you hope to derive any value out of it (and I do think it has some value in small places, like encouraging brothers to take care of themselves both internally and externally) then you will have to learn to absorb the good stuff, and ignore the bullshyt.
Good luck with that though. The gems are rare, and the bullshyt is the majority so...
