I don't think they are saboteurs. We're too small to be worth sabotaging here.

Most Westerners have a deeply internalized liberalism that they can't see as an ideological construct that they were socially engineered into absorbing. This included me for a long time and does, to an extent, even now. It's not easy shrugging off the programming even when you're aware of it. These MGTOW types cling to liberalism's false promise of liberating the individual from the society he inhabits and then externalize the blame for the failure to achieve that rather than recognize the false promise as an unachievable social control.
