As I noted in my first post on this topic, I think it depends to some extent whether we are dealing with living people. Canceling some creep who abused his power over women to get them in bed (we have seen such cases in Hollywood) is one thing. Canceling the entire artistic output of some long dead artist or composer is another.
Nowadays they don't even have to be that long dead. Check out what's being done to Roald Dahl:
Sensitivity readers were hired to scrutinise the text with parts rewritten for a modern audience

Now that's little short of vandalism, if you ask me.
Yes, the ruckus over those statues have made international news. Particularly of course figures like Robert E. Lee, though I see nowadays even Washington gets targeted. I would think one solution there is simply to keep it local, i.e. the people who live in that particular town should make the decision, because they are after all the ones who will have to live with or without the statue. One doesn't need protestors from all over the country to descend on the town in question; it's none of their business.
Also, as with the case of Roald Dahl above, part of the whole point of books and monuments is that they give us a glimpse into how people thought in the past. We cannot unmake history by erasing all signs of it, though such erasure will probably ensure that we'll never learn anything.
