Here in north Idaho we had an incident with ANTIFA not long ago. Word got out that they were coming to Coeurd'Alene. A relatively small group of armed militia stationed themselves all around town and faced them head on. Didn't take ANTIFA long to get the message and high tail it back towards Seattle.
It happened fast. Most locals didn't even know it was going on until it was over. As the word spread it was pretty obvious that there were plenty of locals who would have showed up as support if it would have gone on longer.

Might be a lesson here. Show some guts and hope for the best, but prepare for the worst.
