I've never been apolitical necessarily but there was a point where I naively believed in "we're at our best when we work together" and would vote for people of both parties so that there would be checks and balances. This was on a local level only, I've never voted for a Republican for any federal positions even though I was and would still be if primaries didn't require party registration, an unaffiliated voter. I also don't live in a state that has been utterly destroyed by Republican policies so that probably had an effect on it.
Being apolitical is definitely a privilege, or at least ignorance as suggested above, if you're able to ignore politics and want to avoid talking about them.
