When out of the whole article you point out something that is not the focus of the article and introduce a true and undeniable fact that is (unfortunately) most often used as a way of scoring political points on the Balkan from both sides, that fact does in fact become political.

And sometimes pointing out a factual error is just that. You are now the one bringing politics into the discussion. You are making it worse.

Truth can be (often is) politically incorrect.

Truth isn't just fact, it's also narrative. Trying to separate the two is impossible, therefore truth can often be political.
