I think this response surprises me. My worldview is that, living in a racist/sexist/whatever culture, leftist activist-type people will slip up and do or say stuff that is problematic, but that it is remarkable (with a negative connotation) when people do so. And should be rare.

You comment sounds like you can easily excuse bad behaviour when the speaker is very angry. I *get* bad behaviour, but I don't find it easy to excuse.
