Women don't care to mate with beta male victims of feminism the way the way men don't care to marry a heavily pregnant woman whom they know has been gang-banged, even if they know it is not her fault. She would be a burden and disgrace to her family - even if it is not her fault - who will never get her off her hands because no one will marry her after knowing what has happened to her. This is presumably why in some cultures getting raped and being found guilty of rape results in a death sentence.
This really means that no one cares if they live or die any more. (Sorry, folks, but that's the truth.)
Men with alpha male qualities, being primarily motivated by sex, will not want to risk or sacrifice their sexual privileges and status with women to defend beta male victims of feminism with no property or charisma no woman would willingly mate with and no one cares about other than their loved ones. (Sorry, folks, but that's the truth.)
In a matriarchy, there will be no male solidarity, and it will be every man for himself jealously guarding his own property and privileges, with no thought for posterity or the long term national interest because most people will be atheists who don't care what happens to their civilisation after they are dead.
Men who apply to women for permission to criticise feminism will be regarded as beta male victims of feminism and treated with contempt. (Sorry, folks, but that's the truth.) I have not seen The Red Pill documentary, but the way so many beta male victims of feminism see this as their beacon of hope is indicative of their obvious lack of masculinity. It does not make me want to see it either. I don't want to see it because I have an idea that it will feature crying victim men with mental health issues, and I don't want to see that. I want men to be in charge and in control, and so do rational people, not victims whingeing about their victimhood like women and expecting sympathy.
If Sisters Are Doing It For Themselves, then brothers need to do it for themselves too, without asking for the permission of women or seeking their approval.
