How big of an impact does politics have on your purchases?

[Bleach Blonde Bad Built Butch Bodies for Biden]

None at all, really, because there's a number of businesses that do or have done things I don't approve of, so it would be a waste of time for me to go over every one and decide whether I should give them my money or not.  I mean, I probably wouldn't shop at a Hobby Lobby, but there are (as far as I know) none where I live or will soon live and there are plenty of other stores I can go to for the same stuff.

Likewise, I have no reason to eat at Chik-fil-A when KFC already sells the best chicken.

But, if you're going to boycott one business on the basis that you disagree with the owner's politics, it would be hypocritical not to boycott other businesses for the same reason.  Since one person abstaining from buying isn't going to change, well, anything, what's the use obsessing over it just to feel like you're doing A Good Thing?
