This brings up a few talking points you tend to bring up, so I’ll break it down to see where I’m coming from:
1) “Blacks are the real racists”. Calling them “blacks” isn’t the greatest way to make your point but regardless, sure some black people can be insular toward white people and hold negative attitudes, and in the technical definition of the word, this might be true for some black people (just as obviously not all white people are racists). I’ll raise you that 1) typically this “anti-white” racism comes from a place of fear and stereotyping that exists in their communities (much the same as classical racism) but fear that I think is much more well-rooted in the long list of transgressions white people have made against black people. The second more pertinent point is that racism typically has been only practically meaningful in the context of screwing over black people. Of course hatred from a black person to a white person based basically on skin is bad, but it also doesn’t carry the connotation of being dangerous to a way of life for white people.
2) Democrats are the KKK party. You like to dispute the “party line switch” around FDR which is fair enough. I’ll tell you why I don’t think the Democrats are the KKK party. Look at the geography of republican support and the flags people bring to Trump rallies. Former Confederacy states generally vastly support Trump, to a significant margin more so than former Civil War Union states. Confederate flags make appearances much more often at Trump rallies, and the Confederacy and slavery were strongly associated the geographic regions (e.g. the South) that had higher KKK presence. Furthermore, I think it is much more likely that attitudes endure among geographic, societal and cultural lines (like descendants of the South) than strict adherence to a party line. What did our party do 160 years ago? Well it wasn’t our party, it looks more like it would have aligned with what is currently your party looking at a map and enduring attitudes among your party’s members.
3) Biden supported the KKK grand wizard. I was unfamiliar with this point, so I dug around for around ten minutes and found several articles and fact checkers. You are most likely referencing Biden giving a eulogy to Robert Byrd, who was not a KKK Grand Wizard but only a member in his youth and who had since issued multiple public apologies for his membership in his youth. He called his membership (which was in the early 1940s btw) a “horrendous mistake”. Additionally, if Robert Byrd was such a racist as recently as serving in the senate in the early 2000s, it is interesting to note that the state he represented for so many years, West Virginia, voted 70% for Trump vs 28% for Kamala, and I don’t think racial attitudes switched radically there in the last 20 years. This isn’t a perfect 1-1 correspondence obviously, but it illustrates my point a little. Again, faces and names change but culture moves slowly, especially if there is an insular sense of group identity attached to it.
Sorry for the wall of text, but there was a lot to dispute with this post.
