Maybe you should, because they certainly blame you. I've been reading the most horrific accounts of lynchings from the time they were written in various papers in the books 100 Years of Lynchings (not for the faint of heart and truth be told I can barely stand it). The accounts give various viewpoints of one lynching in April 1899, of Sam Holt in Newnan, GA. Two accounts from the Northern newspaper give three different perspectives of the brutality: one attempts to civilize it some, the other (a black written northern account apparently) tends toward the "uncivilized" truth, and the third is statement from the Democrat Governor of Georgia.
The Governor's is by far the worst, although it lacks the visceral details. His depravity lies in the condemnation of the innocent but in the certainty of unproven guilt and blame on the victim. Governor Chandler says what we have heard since then and including up until today: blaming and gaslight the black Americans. The "scores of intelligent negroes, leaders of their race" approached him to complain of the barbarity of the lynching. He said of these black intellectuals that were saw only "one side of the question" of the lynching, and "are blinded by race prejudices." He is saying publicly that these black leaders are essentially, in modern terms, "playing the victim."
This relates to your point as the lynchings that occurred in the early thirties happened when the racially segregationist laws you described were passed. Those early thirties lynchings has the same M.O. as that of Holt and all those occurred in between: a crowd, stabbing the alleged black man who was not tried in court and often later found to be innocent, cutting of the fingers and other unpolite extremities, burning the alleged perpetrator, then burning and hanging.
You have to remember that up until 1965 the Democrat Party WAS the party of white supremacy. The South was blue, a one party run "country" in its own right, voted solidly for FDR, and none of this legislation could pass without them. Thus, they deliberately segregated blacks out in all of it. Any benefit under the New Deal deliberately and consciously excluded black Americans in the South. Although the language left out the wording of deliberate segregation to not offend the Northerners, the Southern delegates to both Houses of Congress spoke that language openly on the floor to block any attempt at equality from being enacted. FDR passed it all and turned away the head of the NAACP who asked for the lynchings to stop.
We must stop having this illusion that FDR was a member of "progressive" and "liberal" party and was instead head of a party dedicated to white supremacy and pushed and enacted that supremacy from before the Civil War, during the Civil War (obviously since they were the party that started it and were the Confederates) and then after it. The words "liberal" and "progressive" were used the Democrat Party racist Southern members who voted for it, so it is confusing. But you must remember that these words were purely white words and looked to give those "progressive" benefits to whites only. Fifteen states were legally segregated under "separate but equal," which in those states wasn't just a good idea or supreme court ruling but now law. So whites in control in those states were no thoroughly conditioned from excluding black Americans because of the law, Blacks couldn't vote and no voice in this legislation (there was a sole black congressman from Chicago but he had no impact). Of course the middle class was structured in all these laws for whites. What other outcome could there be from a political party in control of lynchings and the law?
So, yes, whites should be condemned. They easily condemned blacks and still do, saying they are "acting like the victims" when in fact it is, I'm afraid, not acting, since the victimizers are the ones saying it. In other words, this the way to tell black Americans to "shut up."
The black writer in 1899 said it better than I and was flatly truthful and accurately outspoken: "The annals of the savage will be seardhed in vain for anything worse than the exhibition given to the world by the white civilization of the state of Georgia" and the rest of the South where those atrocities of law and lynchings occurred thereafter.
Thanks again as always for bringing these laws and this critical issue to light.
