He isn't bothsidesing to say that politics are polarized on both sides. And he did nothing wrong by elaborating on the purity test bullshit on the left. He doesn't even say he disagrees with the left (he did support Bernie after all), he just hates that one imperfect comment gets you dragged on social media. Kind of like this. So he just avoids talking politics. His biggest crime here was using the phrase "cancel culture"
And that is a weird assumption since I never said music shouldn't be political. I said he's within his rights to not talk about it
