Politics are a facet of almost every decision you make, even if you don't think so. Or, I should say, almost every action you take can have a political statement.
And also; even the story of the game we know it is a political statement, in-universe; Becoming a mindflayer (and thus furthering their agenda to rise to ruling the world like in days of old) or fighting back and making a stand for the current status quo.
You side with the druids? Help the dryads fight back against the town that's over-foresting? Pro nature. Anti-industry.
Look at any actions you take IRL; almost any of them can have a political statement in some way. Asking for anti-politics is like asking for anti-story. You need a clashing of ideas and ideologies. If everyone agreed, or never brought up what they're fighting for/against, then there would be no conflict to drive an adventure story like Baldur's Gate.
Also, being anti-politics is, in itself, a political statement.
Also, also, BG has always had politics; you were the offspring of a god of murder, and had to decide what to do as such. Theology and politics.
It's not about being anti-political, just about not using yet another form of art/entertainment as pure political, one-sided propaganda and forgetting about the game itself. Just look at the 3 last Star Wars episodes, FFS...
