You care or don't care about politics, it still influences your life. Back to each individual, but my advice is that you need to learn about politics, you need to have political knowledge so that you won't be fooled later especially by those politicians.
I care about politics but I don't really show it. Although mainly because I avoid conflict, especially with my friends, I also don't want to be 'wrongly' affiliated with a particular ideology or political movement.
With this there will be people who will call me a coward and I have no problem with that. If on an international scale, it is better to buy time for some conflicts than to start a third world war.
