I know this is a problematic observation given what I do all day, but have you ever noticed this? Ever been sitting at a cafe overhearing the conversation at the nearby table where people are talking politics and not thought "wow, these people are fucking idiots?" And I mean that I am sure if people are at the next table overhearing my conversation about politics they are thinking, "wow, what a fucking idiot." This isn't about agreement or disagreement it's just that it's a topic that no one can actually sound smart about in casual conversation, even if they are. It's hard to not sound like you're just auditioning to be an NPR contributor or recycling some stuff you read in an op-ed even if that's not what you intend to do.
I have no bigger point.
