I suppose on the bright side, they've stopped ALL political donations, so that includes donations to progressive organizations.
I still would have preferred Bob's suggestion of totally ignoring these whiners. Publix seems like one of those businesses that just distributes donations across the political spectrum and generally do so behind the scenes without making a big deal about it. That has always been fine with me. I know that some of Costco's donations go to organizations that I disapprove of, but Costco is not in my face about it, so I'm happy to do business with them, just like I'm happy to interact with many people with whom I disagree politically.
