To an extent, but there have to be limits. This NRA Lifer is not bringing Ben and Jerry's ice cream home because it would be obscene. Their management ELECTS to mix their politics with their business. It is their free decision to alienate me. I respect that. It is my free decision to tell them to stuff their politics-blended products, whether they respect that or not.
Now I am sure there are thousands of companies run by people whose politics I despise, but they do not TELL me about it, nor rub my face in it.
Fair enough. If a company chooses to make their product “political,” then those with opposing political viewpoints would naturally avoid it. However, if the private politics of a CEO etc. comes out through no promotion of their own, then that’s their business and not related to the product.
