I’m not saying create an echo chamber, my advice excludes engaging with people who agree and disagree, at least when it comes to large scale politics. If someone wants to get involved in politics, I think they should avoid echo chambers and engage in good discussion. But for people who just want to or need to get away from it, disengaging entirely I think is the way to go. You can still get involved in local polics without engaging in larger politics. They often have direct impacts on your community and it varies wildly between different communities.
This is likely not the best place to get answers for this question.
