My argument is that every institution is political whether it wants or not. Bakery is very obviously political because everyone tends to eat food and as such food is an evergreen political theme. Perhaps this is more visible in some countries than others, for example in a neighboring country the price of butter is a quite common item in TV news (really), and it's not a poor country.

But also other than that, a few years ago there were some articles about a bakery that refused to bake a wedding cake for gays, and it was a public affair for a few weeks. Is that political enough for you?

I just think we are talking about different things. I hear what you are saying, but I don't think that bakeries being tangentially related to politically charged topics make them a political institution. Bakeries also handle and store money, but that doesn't make them a bank. etc. The nature of bakeries as an institution is not political - they are not concerned with the organization of government and policies. They may interact with the government but that doesn't make it a political institution.
