I would agree with this. If there is mass civil unrest it won’t be just antifa vs everyone else.
So that means no need for a militia. I'm not going to leave my home, family and friends behind to go hide in the woods looking for enemy antifa combatants. Antifa won't ever do this. They do not have the will to do battle with the rest of the country. For the most part they stop just short of outright insurrection and instead find one-off circumstances to go after. That means that running away is far more valuable as a skill than speed dialing a militia at that moment.
