If you live in a retreat hut, far up in the desolate mountain ranges, isolated by the vastness of nature, surrounded by fresh air and blue skies, pine trees and the wind, together with animals, then that is your reality, that is how your situation is, and that is what you will have to deal with.
But if you live in society with other humans, then you are part of that society whether you like it or not (and you are certainly not living in a cave or a retreat hut.) And so you should know how to work with these circumstances, because the better you can understand these things, the better you will live your life, whatever way that may be.
So optimally speaking while living in society, perhaps you are a dedicated practitioner, which means you spend most of your time on study and practice. So how is politics then relevant for you? Perhaps it is not what you are most interested in, but nevertheless it is still important. Chances are that in your life at one point or more, you will encounter minor or major points related to politics that are highly important to you, and that means you should know a little about how these things work.
Right now in the US, as an example, something that is very important for most Americans dare I say, is the issue of gun control and gun laws. Why? Because it affects children, and it affects teenagers. It affects their parents, their families, their friends, their loved ones, and in fact it affects many people in American society, at a deeply serious level. Wanting a change here means you have to get engaged in politics, regardless of what level that may be. Because this is how change happens.
And so most of us, affected by things in daily life and society, will respond to some or more of these things with opinions and ideas that belong to the realm of politics. Being that we're social creatures, we enjoy communicating with each others. Agreeing or disagreeing, sharing viewpoints, through discussions. That includes politics.
If you dislike political discussions, simply don't read them. Don't participate in them. But don't say "I am offended", and then try to shut down others and force them to be quiet, just because you don't like what they're talking about. This is behavior worthy of being part of a dark dystopian novel.
