you are not incorrect in your assertions, being that in a better world it wouldn't matter. But we live in a stage of history where ignorance and disenfranchisement are tools of manipulation to keep a population docile, its citizens isolated from one another and helpless.
Everyone needs to learn that politics is not actually optional: it will affect your life no matter where you go as long as there are other people - because even if oneself is not political, those other people ARE. Your boss, your landlord, your banker, your pharmacist, your doctor, your neighbors, your friends and family. Politics Knows Where You Live.
People have power, but all too often they have been duped into not realizing it and lulled into an ineffectual stupor. That cannot be permitted to go on. And if a pop starlet can wake people up and make them pay attention to what's being done to them instead of idly wasting their while on passive compliance to systems that are slowly (and sometimes not so slowly) killing them, then, well, fuck it I'll take any advantage I can get.
