It is not possible to be apolitical. Everything is political everywhere all the time. As you said, those who just "aren't political" are in fact political in that they by their inaction and indifference give support to the current status quo. They support the current regime. As for those people, you can choose to ignore reality but you cannot ignore the consequences of ignoring reality. Eventually it will come crashing down upon them in the form of some intolerable circumstance, and they will suddenly find themselves quite politically concerned after all.
