I work remotely from the midwest for a CA tech company. I was surprised that other people were surprised that there's a confederate flag spray-painted on a car-sized piece of corrugated steel that's been beside the interstate (on private property) for years now that I see every time I drive between two cities. Similarly the number of confederate flag shirts and, recently facemasks.
