An idea: V for Victory?
In the 1930s there were quite a few Nazi sympathizers in the US. (When Nazis Took Manhattan : Code Switch https://www.npr.org/sections/codeswitch/2019/02/20/695941323/when-nazis-took-manhattan)
During WW2, the BBC was using Morse code "V" in their broadcasts particularly directed into occupied Europe. By the time the way was over, the palm out "V" was a widespread symbol of disavowing the Nazi ideals, and for decades after both left and right political sides condemned authoritarian brainwashing (racism itself was a bit more sticky). (https://en.m.wikipedia.org/wiki/V_sign) but recently white nationals have been getting more outspoken and less marginalized.
The V-sign has also been used by the sixties counter-culture to indicate peace... it is probably far better known for that meaning now than for victory over the Nazis.
I think the older meaning resonates with the current "no kings" moment ... don't let MAGA substitute the concept of authoritarianism for the traditional democratic patriotism that won WW2. The flag means allegiance to democracy, not to POTUS.
