I had similar experience. Went to an art installation run by group of young lefties, and upon entering they say: “if you see any racism or sexism, you should come to us and report it”.
I was taken aback and immediately felt uncomfortable. Why did they need to say this? Do they have a problem with racism and sexism? Which would have been unusual because it was a lefty place.
The real question is does any of this stuff need to actually be said?
My view is it just provides cover for powerful people to take out their enemies based on rule interpretations and technicalities.
