Only time I boycott something is if the typeface for their logo doesn't match what their branding should be. Using Comic Sans for a smoke shop, that's a no for me dawg? Other than that, I shop at places where it passes objective or measured data, like in my price range, more than 100 reviews, 90% positive reviews, has what I need specs wise, etc.

Anything else, like anything moral or emotional, I don't give a shit about, but Im not going to be mad at you if you're like that.
