The Left makes mistakes. Learns nothing. Moves on. Makes the same mistake again. And pretends to be shocked if you call them on it.
I would like to see the Library of Congress put all their old copyright-expired newspapers on the web going back 200 years. It would be fascinating to read about the left's buried past. Unfortunately librarians actively "lose" old articles and books that do not conform to whatever mores are in vogue. They feel it's part of their job. I don't think the left could handle letting the general public travel into the past.
