I'm one who doesn't believe political art is inferior, or somehow separate from, other forms of art. Politics and "the human condition" are fused, and it is not very useful to try separate them as distinct entities.
The evidence of the political and human nature of art being fused, in my opinion, is Holocaust literature. No human event demands exploration through art more than the Holocaust. We must attempt to understand it; we must attempt to witness to it.
And Holocaust literature is inherently political. Whatever truths about "the human condition" we can grasp through Holocaust literature only exist within the context of the politics that created the Holocaust. On the other hand, to approach an understanding of the politics that allowed and created the Holocaust, we must attempt to understand "the human condition" that allowed and created such politics. The subjects are not separated, but fused.
