If “that” was a “right-wing counter-protest” then it was a very SAD example. A bunch of older white guys dressed up in camo carrying AR15s ... and when the teenager in a T-shirt moved toward him he moved back. They all retreated until they were left standing on the side of the street watching the BLM protesters stream past them. Either you are serious or you are not ... these people were not serious and were made to look like old fools.
In my book, these things are pretty useless. If you want to get people on your side, get a group together and do good works. Maybe clean up trash from a blighted area or set up something to assist the elderly in a community.
Just standing in the street dressed in camo with an AR isn't doing much but making you a target for these antifa lefties and the government.
