That was my summary. The reply charged racism, intolerance, superiority, hatred, and expressed disgust. I’m not sure how that has a different level of validity than “wow you are so awful”. It’s more specific, but not in a way that suggests that the original article was changed.
I was in danger of not figuring it out — I just had a quick glance at the comments and lucked upon another comment that referenced specific content that was missing. So no, I wouldn’t assume that everyone will figure it out. Everyone who puts in a decent amount of attention will.
