Super, I generally like you and your posts, but you need to dial it back about 30 notches on this one.
Before this thread, I don't remember ever hearing of Harry Golden before (which sounds like it's my loss). I had no idea who he was or what the "vertical negro plan" was before I opened this thread. But I did open this thread and right there in the OP is all the information I needed to understand what was discussed.
There's no hidden meaning here and no "read between the lines" BS. The thread title is simply the title of the story being discussed.
There's nothing racist about the thread title. It is certainly race adjacent because it is social satire covering race and racial practices, but it's not racist. There is absolutely nothing about it that's racist. In fact, the story and the identical thread title is anti-racist in that it calls out racism.
You jumped to an assumption based on your reading of the thread title, but that reading turned out to be completely wrong. In that case, you should have read the thread, realized your initial assumption was wrong, and kept right on going. But you're way out of bounds trying to police the entire thread based on your misunderstanding of a thread based on your reading of the thread title and then calling out others for being racist because you jumped to inaccurate conclusions. Simply put, you're 100% in the wrong here and you really should back down on this one.
