If they were being dismissive probably Pollyanna liberalism. Generally though, since we have a healthy relationship, we talk about the differences in the messaging we are exposed to and discuss the underpinnings of those messages. On many things we have a high degree of alignment in our views.

For example, we both agree strongly that our political institutions have become dysfunctional through partisan extremism. I tend to be idealistic in that I strongly believe the tools to "fix" that are built into the system itself (and can argue that point using the recent election as evidence to support that claim) but they feel strongly that structural changes to how the institutions are built is the best solution.

My extended family has a similar spread of opinion, and I'm glad we can discuss and accept the differences. I think it's important to identify and interact with people you respect who have opposing views.

If you can simply dismiss differences in opinion as based on ignorance, lack of insight, prejudice, echo chamber effects, etc., you don't have to evaluate your own opinions as much.

And repeated exposure to weak opposition to your opinion also serves to strengthen them, with a kind of meme-inoculation effect.

That's a perfectly reasonable question, actually. There's no reason you should have been downvoted.

Being as the whole point to echo chambers (and the key to their magical powers of endurance and efficacy) is that, by definition, those caught up in them tend not to see them as such.
