It is incredibly dangerous to make politics part of your identity and then just absolutely bathe yourself in a political media echo chamber.
If two or three days ago, not knowing he was sick (which I didn't), I had said to someone "That Dilbert guy seems to be sort of a whack job," why would it matter that he was alive to hypothetically defend himself? It's extremely unlikely that he would ever be aware of my comment at all. So why does it matter that he's alive?
