When we throw up our hands and say none of it matters, we're doing the fascists’ work for them. They don't need to hide their corruption if they can convince us it's pointless to look. They don't need to silence truth-tellers if we've already decided truth is meaningless.
As I posted in the blog comments, I can't imagine being in a position to not care about what is going on in politics. I'm documenting the Trump administration's actions on @wikipedia so future generations (or extraterrestrials) can see where and why things went wrong.
