I honestly don't see the point of re-visiting 70 year old "news".
My grandfather (born 1889) was a member of the Klan. Not especially relevant to me now.
Nor to any other rational person.
The point here is that "these guys" will fall over each other to scrape and grovel about something that happened centuries ago, but something even more barbaric that happened within living memory is "No Big Deal. Everyone Was Doing It."
It would be if you were running for office:
