There's a difference between the stated philosophy and goals of a group and the behavior of the people in the group.
The philosophy of MGTOW makes sense. Not giving in to society expectations on what a man should do and who he should be. Not feeling pressure to be married or in serious relationships, not feeling the need to be some sort of "provider" for women that may or may not appreciate it. If you got a homie that's older than 30, that ain't really looking for a relationship, that's basically a MGTOW mindset. Society is expecting him to get married and he's like "eff that, I'm gonna do what I want"
However, in reality most of the dudes in MGTOW are bitter guys that don't get play from women, or guys that got screwed over in a previous marriage. Although I agree with a lot of the philosophy, I personally could not be part of any of the groups or even frequent the websites because it's too much wining about women. I don't wine about women, they are what they are. Now if they are on some bs, I will call it out, but I try not to make negative generalizations, versus just noticing what the majority of women I've encountered have done.
