I guess two main crowds of MGTOW are those that are men that had gotten ran and had their hearts trampled by their girlfriends, or wives. The second being incels in-denial when they harbor their hatred upon women for simply not getting a date; they only swallowed half of black bill capsule and hasn't feel swallowed. A lot of them realize what's happening around, but are not accepting their faults at defeat.
Yes, some concepts do overlap. However, there's a few things are holding them back and someday, i.e. being the wall concept, I'd wish they'd take more of a nihilistic approach like us and possibly see things to a nothing but a meres end. Anyways, its a good support system for volcels and I encourage volcels to participate in that rather than being a part of inceldom.
