What Blaze said, or make sure your on an instance that suits your interests and rely on Local tab as the filter.

Be it Nation (like myself at aussie zone), or special interests (like the instance “vegan theory club”). These instances Local feeds are very different from All Lemmy, and days often go by without any passing referal involving US politics.

It doesn’t mean you can’t participate in the All tab discussions trending across the Lemmy instances, but it does mean your own Lemmy instance provides a kind of safe harbour, or comfortable place to retreat to when the trending posts get too much.
