Loving your neighbor (business) despite their politics

So I'd like your input on a hypothetical, (based on some facts that turned out not tell the whole of the story.) One of these many new local coffee shops opens near you, and let's say you find out the owner supports a political leader you're very opposed to. As someone who believes in supporting local independent businesses over chains and e-commerce, do you visit and support it and spread the word to build it up, or do you avoid it because of the owner's politics? The question for me personally becomes how much do any politics or influence of the owner extend into and beyond the business itelf, at which point boycotts make a bit more sense. What are your thoughts?
