And as someone who lives in one of those areas of the country constantly scorned, belittled, and caricatured, I can say with confidence that you do not want those people to act in kind to Antifa.
There's been a lot of living vicariously through Antifa/BLM lately with portions of society that want to "stand for something." It's the same mentality as people who wear Che Guevara t-shirts but complain when the wifi on their plane isn't available.
On the other side of that is a enormous, peaceful, patriotic section of U.S. society that is heavily armed and competent with those armaments.
If you make this segment of society feel as if they are the enemy of the country they love, it will be a disaster. If there is ever armed conflict between urban areas vs everyone else, "everyone else" in the U.S. will win overwhelmingly.
