I have to admit; after having watched these Antifa folks girding their loins for combat, I'm a lot less worried about their capabilities than I once was.
Bottom line: most of these guys would get curb stomped in a straight-up street fight, which I'm sure not one of them have ever been in, let alone your standard everyday bar fight. Or even an after-grade-school rumble in the playground. ;-)
Also, there's no such thing as a fair fight. If you go into a hoped-for riot thinking that either your opponents or the cops are going to fight fair you're going to get a beating thrown at you. Me, I'd pick up a brick and hit you from behind if I could get away with it. Or kick you in the Trump-balls from behind. I usually make that tactical decision just before I make my move. Hahahahaha!
