There is no avoiding doing business with anti-gun companies. There are way too many of them to avoid. Just one: Ford. Are you going to trash your truck or car now?
You do your best. Just like GE Capital does its best to not do business with firearms companies, but can't avoid doing business with WalMart. We can still target certain companies to shun. Is it fair to shun some anti-gun companies and not others? No. But, I don't care about fair. Target the weak or small anti-gun companies that are easy to boycott.
