Nope, I know exactly what so called 'cancel culture' is. What I find remarkable is that Republicans constantly insist its only the Dems that ever do it, yet fail to recognize when they themselves are guilty of such. Gerrymandering - intended to suppress blacks and/or hispanics from voting - is one form of cancel culture. So too are any laws Republicans put forth in any given state that makes it harder for blacks and/or hispanice to vote because they know most of them favor Democratic principles.
Nor should it be forgotten that the Republican party is currently not only centuring those within their party that stood up for honest and ethical principles that went against Trump's cult but further, seek to primary them in the next election and/or destroy them personally and professionally for having done so.
