Politics dictates so much of daily life, at every level, that it's important to be able to have conversations about it. It's frankly self-righteous to see yourself as the one person with nuanced opinions in a crowd of simpletons, and while I do think that politics in many liberal democracies has become more polarized, you'll never restore nuanced debate or good-faith disagreement in political discussions by just avoiding the topic.
I'm not advocating for politics being the only thing you talk about with your friends, but if you and your friends are able to have useful discussions about the impact of some policies over others, can have constructive disagreements over reasonable political discourse, and can identify larger problematic trends in politics, a lot of good can come of that.
