All the issues other than abortion, obviously. I don't see the problem. It's her personal boycott, she can rank personal issues as she chooses. It's not unreasonable to see abortion as the top or only priority, even if you disagree with that.
I normally don't care about politics when I'm shopping, but I make exceptions for Jimmy John's, Hobby Lobby, and Chick-Fil-A because I find them especially odious. But I know that lots of people are pro-life and anti-gay. Am I supposed I take that into consideration, and not boycott them? Or maybe give equal time to them, and boycott pro-gay companies too?
If I don't care what other people think, am I elevating myself and my holding my convictions to be superior? Do I need to drop my belief that politics ordinarily don't matter when shopping, and start researching the political actions every single company I come across?
I don't think so.
