John Oliver is a good comedian, but I don't value his political opinions above those of a Kardashian.
If a team like that is wrong about something, it's not for lack of trying to be right.
I've never cared for the format. Just gimme the bullet points, save the snark.
But I've also understood that I'm not the audience. Leaning into civics and current events is a lot of work. And people are busy.
John Oliver, Michael Moore, John Steward, many others, are quite a bit more accessible for a wider audience. So they are a vital part of our public square.
TLDR: John Oliver is awesome.
