I left the US several years ago for the expat life in SE Asia. Sometimes I feel like I’ve lost touch with the US, specifically California, more specifically Monterey. When I hear a story like yours, I am shocked on several levels.
Keep buying coffee. Keep going outside the house and interacting with people.
If this is what has become acceptable social behavior, I’ll continue to live in a predominantly Muslim, non-English speaking nation where I am an old, white, male, minority of one (in my town). I seem to be getting a lot more respect than was shown you.
Good luck with getting on with your life and your message.
