Your question presupposes that MGTOW IS a smart way to go. Thus, your starting point is flawed. The question should be, "Is MGTOW a smart way to go? I would say that in 97% of cases or more, MGTOW is definitely not a smart way to go, especially for men who have never married, had children or even dated much. Followers of the movement consider it a panacea for their bitterness. But in fact, most followers fail to recognize their underlying problems, which generally have to do with insecurity and a fear of rejection.
So along comes MGTOW, which gives you permission to forgo having to grow up and do some self-reflection and instead spend your time having sex by yourself in front of your computer. What a pathetic way to live one's life. MGTOW, in nearly all cases, is not a smart philosophy. In the end, it is destructive because once a male is hooked on internet sex, he finds that he is physically and mentally unable to have a relationship with a live woman. He then becomes more self-loathing than he was before. However, he directs all of his anger toward women.
