MGTOW is the most misunderstood concept, because it's not a movement following a book of rules. It's Men Going Their Own Way. My own way was becoming Christian in the one of the most atheist societies of the world.
The most important point for many MGTOW is refusing civil marriage. Civil marriage is degeneracy, it's a revocable contract to legalize fornication.
Civil marriage is the enemy of Christian marriage, (a bonding of man and wife for eternity, which cannot be divorced). Civil marriage didn't exist until the 19th century.
