I think you have zero idea about what MGTOW actually is, however, I don't blame you for this because there are a lot of women-hating MGTOW out there. The attack on the nuclear family is not from MGTOW but societal laws that weaken any motives towards having nuclear families and de-incentivise men from participating in a sham that ultimately will destroy their sovereignty over their resources and freedom.
Here is the real kicker, many think going back to a traditional trad-con societal structure will fix the problem and it is not going to fix the problem. There needs to be a new societal model and I don't think it is going to be nice. It's going to be more nationalist or statism-like whether we, in the west, like it or not. The non-western nations are going to adopt this model and the west will either follow suit or be over taken and then have it imposed upon us anyhow.
