What will be next?
Gas stations and steak restaurants (or whatever businesses are considered conservative/republican) refusing to serve democrat/liberal customers?
AT&T refusing Internet connectivity to abortion clinics?
Having lived through a year long political crisis in Hong Kong, this is actively happening right now. There's even a whole "yellow economic" (meaning, protestors) where they support businesses who also support them. Some of these businesses refuse to serve customers who don't speak Cantonese, or even recently refused to serve customers who wear a government issued face mask.
Businesses who were considered "against" the protestors, got trashed or set on fire.
Whatever their political stance is, I personally refuse to go to any business who's actively refusing to serve customers based on their political stance. You wouldn't feel right refusing customers based on their skin color or religion, so why do it based on politics?
