This group of individuals is about to go through some shit
Trump has all the cards.
They played their hand wrong.
Now they all pay.
They overestimated the disdain for Trump amongst the rank and file average hardworking black person.
They have unleashed a beast they will never, ever have control of ever again. They have zero idea of what they actually created. I really doubted the way this was all playing out for a long time. Now it is coming into focus and it is fucking sexy AF
I think rational people understand that hand gestures can be interpreted subjectively and most often are.
However, the "white supremacy" angle was born on this platform.
It then was bastardized and the internet does what the internet does and here we are.
I agree with your premise that their symbols are being dismantled.
