Here is one thought I have about the push to remove statues of historic figures, such as Thomas Jefferson, since he owned slaves.
Society has evolved a long ways since owning slaves was the norm. In some ways, it has improved significantly from early 1800s to legalized gay marriage.
Figuring out how to remember our past, when social norms were so different, is a challenge. It is still important, tho, to remember and realize that humans are capable of not only great deeds, but also great horrors depending on the context we find ourselves in.
We have progressed in many ways, but we still have similar faults that lead to things like creating conditions leading to homelessness, cliquishness, stranger danger fear, mob mentality, false accusations and mean spiritedness.
