I'm not sure what point you think you are making here. I already agreed that their owners are bad. I already agreed that people who eat there don't care about the other people who are hurt by the owners' policies/practices. And racist fuckheads account for a minor percent of literally every business that has ever sold a product.

Also, I would be careful equating the owners of a large corporation donating money to anti-LGBTQ+ organizations with Jim Crow laws. There's just a slight difference in level of impact, and it might be offensive to a large number of people.
