MGTOW is for people who are fed up of gender bias in our laws which allows men to be falsely accused but do not allow men to seek remedy from law when they suffer. MGTOW hates the idea that it is okay for men to suffer in the hands of evil women who can steal and sell the kids, puts false accusations on them which can put them and their family in jail. Also, it rejects the idea that woman is a weaker and fragile sex and consider women as strong and capable as men in committing a crime. MGTOW insists on treating men and women as well as mother and father as equals in all respect especially in the eyes of law and dislikes the idea that mother love children more than father or mother cares more about children than father. And until that equality is achieved, MGTOW is the way to go.
MGTOW movement is not for misogyny but it is against misandry and against gynocentrism where female is considered as far superior and sacred to men and to be always protected from evil dark men lurking in the streets raping children and women. It has become crime to be born as men and MGTOW recommends men to be united again to fight for their rights.

When you think up something brilliantly righteous while baked.

Men who have done a cost benefit analysis and realized that cohabitating with or marrying modern women is not worth it. Often men who have had negative experiences with women in the past. But could also be men who have taken up the lifestyle due to listening to men who got taken to the cleaners in family court. People try to paint them as INCELS or losers because when women want to focus on themselves they are "strong, independent, and empowered" but society loses its mind when men are not slaves to pussy.

Men go their own way.
Generally a group of guys who (while yes some are hard incels) simply hate dating and often are just men who hate dating.

Women said that they need a man as much as fish needs a bicycle. So MGTOW is a group of men who agreed with women and stay away from them completely.

MGTOW - Men Going Their Own Way - is a statement of self-ownership, where the modern man preserves and protects his own sovereignty above all else. It is the manifestation of one word: "No". Ejecting silly preconceptions and cultural definitions of what a man is. Looking to no one else for social cues. Refusing to bow, serve and kneel for the opportunity to be treated like a disposable utility. And, living according to his own best interests in a world which would rather he didn't.

In other words . . . common sense for men.
