I find if you prod people about what they mean by this, in person rather than on Twitter, often they don't really know. If you prod them about how you can make policy decisions without looking at an issue in some real detail and with some real rigour, they don't know.
It's a bit odd, because they are adults, often educated, in professional jobs, they know that you have to think about things clearly to make good decisions.
The other thing I've noticed is they tend to see issues almost entirely based on what are considered truisms about other issues. So, they say, separating all men out for safety is like all separating black men out for safety which would be racist. There is no ability to talk in a calm way about what the similarities or differences between those things are, much less explore questions about what they think is racist.
I used to know a guy who was kind of a crazy commentator on things, and he contended that a lot of our political language now functioned to prevent thought rather than facilitate it, and he put all the language we use around race, sexuality, etc into that. I've started to think that for all practical purposes, he's correct.
