Prior to 1990s, the Humankind was not split into Mankind and Womankind...
History of Mankind separate from history of Humankind began in early 1990s with men being defined as Evil. Second Wave Feminism did fight for Gender Equality in many ways. Unfortunately, the rise of Misandry coincided with the rise of the Second Wave Feminism. Misandrists view man as Privileged Oppressors. Many Misandrists view men as The Other or The Enemy. Such views were rare at first, but they became common by 1990s and are much more common now.
Men have been portrayed as idiots in Comedy shows since 1990s. Men have been mostly portrayed as villains in movies since 1990s. Male bashing has been common since 1990s. Articles condemning all men are very common in the Mainstream Media. Hashtag #menaretrash is extremely popular on Social Media. Every day, some hateful generalization about men is getting over a hundred thousand likes. Women who kill men for infidelity are applauded by many women and even some men. When Emily Javier tried to decapitate her boyfriend with a katana for infidelity, many women in the comment sections expressed support for her. Most men expressed amusement and joked about the choice of weapon. No one in 2010s would excuse a man who even insulted his wife for infidelity. Obviously the readers who applaud senseless murder of men view all men as The Enemy.
Vilification of men has taken a severe toll on the way men are treated in Society. Some women and even some men view any injustice against men as morally acceptable and ethical. Discrimination against men appeared along with demonization. Since 1990s, many male victims of Domestic Violence have been arrested and convicted as Primary Aggressors. Since 1990s, Family Courts have deprived men of most possessions on unsubstantiated allegations. Now, a man's career can be destroyed by a tweeted accusation from his former co-worker or acquaintance. Presumption of Innocence as applied to men accused of Sexual Misconduct has become a dirty phrase in many Progressive circles.
In 2019, most men do not view themselves as a part of a distinct Class with distinct interests. Most men do not view an attack on men in general as an attack on their Identity. Many men have extremely negative view of Mankind or Men as a Class. Most men have no class conscious or solidarity with other men who are being demonised and subject to discrimination. Most men are ready to accept a tweeted allegation against any other man as a proof of guilt.
Hopefully, sooner rather then later, most men will understand that they are a part of a class which has been subject to severe vilification and moderate discrimination for decades. In the language of Men's Human Rights Advocates, that will be the first Red-Pilled Generation. Then and only then can the History of Mankind take a turn for the better. In my optimistic opinion, it will take 20 years of escalating vilification and discrimination for a Red Pilled Generation to appear.
The Mankind of Red-Pilled Generation will take a stand for Equality. Men will not view women or Womankind as the enemy or the Other, but they will advocate for their own Fundamental Human Rights. When most men will take a strong stand against Vilification of their gender and Discrimination against men, situation will improve drastically. When the majority of men will protest the injustice, many women will understand them and some will join them. Most women like most men are Good Human Beings. Hopefully, True Equality and balance can be restored to Gender Relations. Hopefully, Mankind and Womankind will be joined into Humankind once again.
