Even if you are the kind of person who sees yourself as totally apolitical, on some level, you are involved in politics, whether you like it or not. Of course, we’re talking here of politics with a small p. That can cover anything from where you buy your fruit to how you feel about God or the lack thereof of an omnipresent being. You don’t have to be an expert on Obama – or even have an opinion on the guy – to be political. At least, that is the case with small p politics.
Politics with a big P is an entirely different story. If you claim to be that kind of expert, then you probably are extremely familiar and would be confident to discuss America’s electoral system (versus that of the one used in the UK which is entirely different); when your local elections are taking place; and the laws of abortion and speeding in each of America’s 50 states. You might even be thinking of running for a political position yourself at some point. In that case, you for sure would be the kind of person who is involved in Politics with a big P.
Either way, it is a matter of preference and priorities. Some people are just not bothered about how their state is run, or just do not have the energy or will to get involved. Still, even those people are not apolitical. Everyone has an opinion on something that is somehow connected to politics, even if it is politics with a small p.
