I should maybe clarify - I don't find their veganism to be problematic. I just mean that I can sing along to songs like 'meat is still murder' without agreeing with that specific bit. But then the song 'nation states' comes on and I'm back to walking hand in hand with them waving an anarchy flag.

[Edit to add:

I never really considered veganism a political view…

I don't necessarily consider it a political view. But it is a moral view, and the places where morals bump up against each other is the political part. To me.]
