Maybe a little background as I am familiar with the area and some of the conversation is hard to hear. Apparently, this guy had been around a gun shop in Jackson, MI for a couple days taunting customers with his camera trying to get some kind of internet-worthy reaction.
In my opinion, the wannabe antifa/jihadist (he was calling the man in red racist and speaking Arabic words, but as you can see at the end of the video and can hear them say that he is not middle-eastern, but white) got more than he expected. He wanted to get a rise out of someone, he wanted to get some guy loosing it. Well he got that. It seemed that it got a bit out of hand to him and he started acting like he had a weapon, but still did not back down. He seemed to get in over his head and realize it and was in bluff mode. He then bugged out. That is where it should have ended IMHO. Granted, no one should have reacted to this guy. He should have been left alone to look stupid. How about that for a viral video? Just a video of the man in black acting stupid, trying to instigate only to see people to ignore him. But the man in red got in trouble when he touched and pushed the guy. Nope, let the guy go. But he pursued and continued to get physical. Bad idea. In my not so expert opinion, he met the guy with disproportionate force. While we dont know what happened during the time between the running away and the videographer catching up with the situation, it certainly looks like assault by the man in red. Whether the guy in black deserved it is irrelevant. On the plus side, searching the news and reaching out to contacts that I have still in the area, there is nothing to suggest that either party was charged with anything.
So, now to the point. Imagine you are in that situation, and like the responsible person that you are, you are carrying your firearm responsibly. As a self-check, how is your control when met by a man getting in your face and spewing all sorts of hateful things? How would you react if you were the man in red and faced with the possibility that the other person in the confrontation has a weapon even if they have not yet produced it? Do you have a different read on the situation? One final note, the location where it starts, the outdoor dining, is a brewery. They have very good food.
