Let me play Devil's advocate to your point. She didn't say some groups are better. She said groups are different. Which is true. In some circumstances those differences, when ignored, cause mayhem, dysfunction and violence. Things we are told the government will protect us from.

More to the point her detractors want her cancelled because they think she referred to immigrants as litter, by which I assume they translate as trash or equivalent. This is rhetorical manipulation, something academia should be immune from.

So historical abuse is irrelevant.
