Well, here’s the thing. My dad is a liberal. If there is a liberal cause, he espouses it. Yet, when you talk with him about WWII, or the atom bombs, he admits there was no other answer. It had to be done. Also, when he saw a perp open the door of a car just before him at an intersection, my dad put his car in park, jumped out and grabbed the bad guy and physically stopped that robbery. My dad who is not gun-toter by any means! He will stand up against bad guys. The antifa crowd does not count on people like that.
Sounds like your dad is a manly man. Not going to put up with violence in his neighborhood.
Antifa should have been the best thing that happened to the Republican party. And probably was if we ever get honest votes.
