They used to have these rallies in the Old South. But back then it was because whites heard a rumor that a black man had disrespected a white woman or something like that. A mob of Old South Democrat whites would rally for the death or jailing of the black man. It would be all emotion without any thought that the man was innocent until proven guilty. I guess everything old is new again — just as in the past, Libs/Dems have turned into a lynch mob demanding blood.
More whites are killed every year in black-on-white crimes than were killed in the entirety of lynching in America, which also included white victims.
