It's funny you bring up not debating your neighbours and posting online. This happened to me a few days ago. My neighbor who introduced myself to started asking lots of political questions. I didn't agree with the apparent viewpoint, but it was clear I would never change her mind, so I was just politely trying to get out of the conversation. I think the internet gives the illusion that you might find someone who will actually debate? Like it's easier to ignore that you probably aren't changing anyone's mind.
