My preference is a tactical retreat from the front, followed by flanking maneuvers.
Give up on the ANoVA battle flag. But do what the Left does when it’s symbols become politically inconvienient: swap them out with other symbols.
See my post above about the “Big Red” flag. Excellent example of fighting back through subversive means.
There are HUNDREDS of various “Confederate Flags” that cab be cycled through. Make the LEFT have to fight over each and every one. It’ll tick them off, chew up all sorts of their time and resources, make them look like idiots and we can enjoy ridiculing them whenever it takes them a long time to figure out that we’re just taunting them with yet another flag (meets two of Alinsky’s Rules ...)
