I used to like the MGTOW community, because they were the first to explain female nature to me.
I agree with what they say about female nature, I agree with what they say about gynocentrisim, and I agree with them that men are disposable in the eyes of women and society.
However, MGTOW's say that you have to seek internal validation - which isn't wrong - but most MGTOW have above average intelligence and redeeming qualities that most incels lack. That's why I was wrong to idolize Tesla; he disavowed women (even claimed he destroyed his sexuality), but he had the redeeming quality of having a brilliant mind.
Very few incels have redeeming qualities that they can use to create a new/meaningful life outside of women and relationships, and thus trying to form a new life outside of women/relationships/societal competition and approval is either extremely difficult and depression ensuing.
So in conclusion, when men have little success with women, and are on the bottom of the societal totem pole, but have no redeeming qualities (i.e. a high I.Q or athletic skills) to cope with or build a new life on, he's likely to become very depressed if he rejects female/societal approval, or fails to aquire it.
Otherwise, I agree with MGTOW, but it's clearly not for everyone.
