On top of that if you strictly want avoid political topics, be aware that there are forces who profit from making topics "political" that probably shouldn't be.
So when someone else decides which topics are politicized and you want to avoid political discussions — congrats you just let others decide about which topics you are willing to discuss.
My opinion is that most topics have a political dimension anyways, also because most topics have a economic dimension. Or phrased differently: Everything is political.
When discussing politics with friends the "how" is probably much more important than the "if". Most people do not have a vetted political opinion, they just have a strong vibe that they can't really reason about. They aligned with some sources and read/watch news they like to hear and that forms their image of the world. They never really tried to form a logically coherent worldview that is backed by facts instead of pre-filtered annecdotes that may or may not have happened in that way.
With this as the starting point a healthy political discourse isn't possible. You can't argue against someones vibes.
But that doesn't mean good/interesting political discourse isn't possible. It just means that if someone lets the politicians turn them into a vibe-based party-before-issue follower that uncritically believes most of what politicians say, they can no longer think or discuss the topics that impact them with others on a reasonable level. And this is why topics get politicized in the first way.
And no-one is immune to this, especially not you guys over there with that two-party system. But we all need to remember that towing the line of a political party means they no longer represent us, but we represent them. Mental flexibility translates to voter agency and our democracies hinge on voters being well informed and not throwing their agency away.
TL;DR: Not discussing politics and blindly towing the party line is like throwing your own agency away.
