I would go further and claim that anyone who sees themselves as "apolitical" just basically thinks their own opinion is the only true way to see things "rationally" (and as such "fact" and not an opinion; nothing to be "political" about), and everyone else is just plain wrong/mistaken. Since they're not ready to admit this to themselves and others, they hide behind the "apolitical" label. Otherwise they would see that their own opinion is a "political statement" on equal basis as others. It doesn't even make a difference if you voice it or not.

This strategy works poorly to avoid conflict and friction (life), since one just shifts conflict to reappear elsewhere. Hence the often claimed need to self-isolate "for mental health" to avoid getting in contact with... positions such as one's own, and half-suppressed anger at all those that just don't see what is RIGHT.

Hint: It doesn't work.
