I would say it is tribalism plus Marxism. Groups versus groups plus oppressed versus oppressors. Marxists, communists and democRATs (I repeat myself) use groups that are stirred up into hatred by perceived injustices to attack the other groups who are the oppressor ideological opponent. Just as Saul Alinsky taught to community organizers like Hillary and Barry.
HOW POPULAR IS HE? For his (gag) inauguration, the beloved Biden:
<><> called in thousands of armed Ntl Guard,
<><> the "most popular man in America" hid behind a walled-up White House,
<><> Biden got (cough) "elected" by 81 million votes,
<><> his inaugural had no parade, no marching bands, no Inaugural Ball, and no cheering crowds.

Mr Popularity wasted no time flexing his decrepit muscles to intimidate pesky American patriots who smelled a fixed election.
