words that irk me

What do you mean by saying, "and have it taught they were evil racists".........................They were evil racists!!!! Just because it was acceptable in those times does not make them NON-RACISTS"!!!! Therein lies the problem with the "Cancel culture" terminology.............trying to rename something to make is sound OK or acceptable just because some in society found it "acceptable". I'm sure the slaves didn't find it acceptable or did the black folk not have a seat at the table???? You need to look at it from both sides, not just the side you want to see it from.
I think the point is that we must learn from history, so that we may not repeat it. While they appear to be "racist" in today's terms, and it is certainly arguable that it may well be true, if we remove all traces and records of the past because we find those behaviors offensive today, what will prevent these atrocities from happening again? If we do not learn from our history, we are doomed to repeat it. Just my .02, and I apologize for hi jacking the thread.
