Normal, emotionally stable people do sometimes make decisions about what businesses to patronize based on the political leanings of the business owners. Same thing happens with art appreciation, movie/TV watching, and plenty of other things. Zig might not be a business, but the same rules apply.

Maybe with issues like abortion or racial discrimination, but not tariffs.
