Sociopathic? Its basic logic, if you are consistently treated in a certain way, its only a matter of time before you start treating others the same. If those MGTOW individuals who follow the "I don't owe a woman anything for my time" philosophy are sociopaths, then so are the vast majority of women.
Now, I personally feel that relationships are a partnership with defined expectations for men and women within the context of the relationship. Thats how I and my wife live our lives, but that isn't how most women who have grown up on feminist "girl power" live their lives, and it's reached a point in the west where we are seeing men decide that if the game is rigged they either aren't going to play, or play by the same rules that women use (IE extracting value from the relationship as opposed to building value, which is what most feminist women do), to simply dismiss it as sociopathic ignores why this is happening.
