Some people say protestors becoming violent, vandalizing, and looting are isolated incidents by a few bad eggs, most of them are doing the right thing.
Really similar thought processes go into those two, usually by people you can sort into camps of opposing worldviews. They're both right and both wrong, but it's surprising how similar the lines of thought are and how people can't see the other side is thinking just the same way.
It's dangerously to boil down the arguments from both sides and say, "Look, these two things are the same!" because even if both sides were saying, "It's a few bad apples", the implications of that would be wildly different.
