Companies that cross me politically end up on my shit list.
I'd get a little more sophisticated about that. It's a divisive tactic socially, and while I'm sure your time for research is limited as is mine, there are probably better proxies for confining your business to responsible entities. Business relationships between politically opposed people are a bridge that keeps us together and just might even end up in some constructive dialogue.
I don't have a problem doing business with people who have different beliefs than I do, and am happy to do business with companies that shut up and stay out of politics. But when politically opposed people bring their politics into business, or like this guy, spam business contact email addresses with political messages, they end up on my shit list.'
For example, I was aware Bill Penzey Jr. was a lefty, but I liked their spices and so I still ordered from Penzey's -- then he spammed his customer mailing list with anti-Trump rants back in 2016, and lost my business forever.
Amusingly, the company I switched to, The Spice House, is run by his sister, who stated “Politics does not have any place in my business .. I sell spices,”
