I can’t imagine owning a business and actively promoting your willing to give up sales because of some random person’s beliefs.
I fully understand consumers not shopping at a store that puts up signs you disagree with, you can just go to another one.
Nothing wrong in believing in and supporting the good things. I just think I’d not agitate customers if it were my business.
I quit artificial sweeteners last year. Just use real sugar in moderation. Seems to be working for me. Biggest change is switching to water to drink. Once you conquer that the rest is cake.
