Yeah, agreed. Probably the closest to a black democrat at the time was WEB Du Bois, and that guy is a Communist and closer to a member of the Socialist party than a Democrat. Now, WEB Du Bois, unlike MLK, actually IS confirmed to be a Soviet agent, openly rooting for the Soviets every single dang time.
Also, the original topic is tapes regarding MLK being involved in a rape, not whether or not he was a communist (which I still doubt, as much as I think he’s got far too many flaws as it is). In any case, given that he served as the inspiration for Aleida Scott King’s pro-life views and he was extremely pro-life or at the very least strongly anti-abortion in life, I find it extremely unlikely he would have supported rape, or laughed about it. Actually, if anything, if he loved rapes, he would have supported abortions as a way of “cleaning up evidence”. Besides, that would paint the FBI in a bad light as well and goes at odds with history regarding Hoover’s views on King (knowing how anti-King Hoover was, do you REALLY think he’d just sit on a potential goldmine to discredit MLK? He played a massive role in the McCarthy hearings trying and convicting Communists. I seriously doubt he’d just sit on something that would expose someone he didn’t like as a would-be rapist.).
