I grew up in a blue state, California. California wasn't always blue but they turned blue in my later teens and really never looked back. Even the couple of Republican governors they had more recently were very left leaning (Gray Davis and Arnold Schwarzenegger).
I wasn't born there but my family moved there when I was about 5 years old and I lived there most of my life. My wife was born and raised there. We left California long before all of this insanity hit. Our last 3 years in California was in the SF Bay Area. We're from So. Cal., east of Los Angeles.
I think I would have a much greater chance of seeing this nonsense in the Bay Area then I ever would have in So. Cal. Maybe downtown areas of LA and probably some parts of the San Fernando Valley but the rest of So Cal I doubt I would seen any of this silliness.
Plus I'm in my early 60's, I would think this would be something only the teens and 20's would be doing.
