Normal, emotionally stable people don’t care if the creators of a programming language disagree with them about tariffs.

I can't find any evidence that the creators of Zig hold the views GP seems to suggest, but I think your assertion is wrong.

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.

You may think that's foolish, and not make your decisions that way, but it's a perfectly valid way to make decisions.

Normal, emotionally stable people don’t drive business towards people they disagree with politically. You see that all around the country.
