One thing I do object to is judging past people by today's standards. If you do that, then you have to condemn Thomas Jefferson because he was a slave owner - and that obviously overrules everything else he did. Doesn't it?
I strongly object to that too, and people DO condemn Thomas Jefferson for that reason.
A ridiculous example of that which is local to me, I live in King County, it was named after William Rufus King, however around 20 years ago a group of local politicians without a vote from the people decided to retroactively change the namesake to MLK and the county seal to a picture of him because William King was a slave owner. Now I have nothing at all against MLK, in fact I quite admire him, but he visited King County briefly only once in his life and he had NOTHING to do with founding it. King County is located in the state of Washington which was named after our first president George Washington who like many in his class at the time also owned slaves. I have joked that they should change the namesake of my state to Denzel Washington except I don't say that too loudly because I don't want anyone getting any ideas.
I am very bothered by people attempting to erase and revise history by quietly making edits like this. I don't know much about William King nor do I go out of my way to honor him, but the county was named after him, he did live here and was influential at the time, and to change the namesake in modern times for nothing more than political correctness is tantamount to lying. I think it's totally unreasonable to assume that any of us today, had we grown up ~200 years ago in a region where slavery was commonplace and widely seen as acceptable would have some innate belief that it was horrible and wrong. It's unfair to judge historical figures against modern cultural standards. We are all products of our environment and upbringing, morals and ethics are taught, not innate and everything is relative.
My nearby city has a proud recent tradition (over a couple of hundred years old) of riots that have occasionally changed the law of the land. The latest were over a slave transporter, Colston, who was also a city benefactor - his statue was dumped in the harbour, and his name is slowly being erased from locations.[1]
The local unelected city elders (think local Freemasons on steroids) repeatedly refused to allow explantory plaques to be attached to the statue's plinth. I'm not sure of the reasoning, but they probably didn't want attention brought to their past activities.
My preference would have been to have plaques everywhere associated with Colston, and to use them as a trigger for discussing the city's inglorious past. Now those triggers are missing, it will be easier to forget history. Not, I suspect, what the protestors and SJWs were aiming for.
[1] i suspect that in part Colston was merely a "Marlon Brando trigger", i.e. "Hey, Johnny, what are you rebelling against?" "What've you got?".
