I ask the same thing... as well as why the Trump flags. It is a lockdown protest. the group could get a shit load of democrat support if they didnt make it look like a trump rally. my daddy used to say... if you insist on hitting yourself in the head with a hammer, dont come complaining to me when you have a head ache...
On the other hand, if someone would like to produce some really powerful optics, have a person with a Biden flag, and another with a Trump flag, marching arm in arm, preferably with rifles slung across their backs.
