In reference to the idea that businesses should be able to refuse service to whomever they choose, I’m sorry to say I agree.
They should be able to pick to whom they offer their services.
I also wholeheartedly agree that there should be some way to readily identify those businesses.
I love the idea of window cling or something similar that they can proudly display to show their views. It will help me readily identify which stores in town will get my dollars and which will not.
It’s so sad that our society has come to this. It’s just one more form of bigotry.
