I'll agree with you up to a point. I don't read TenNaple's comics (More due to the fact that they aren't exactly mass printed than anything), so I can't really comment on if he's reached that point yet. Some artists due, however. See Orson Scott Card.
My point is, once you let your politics enter your works, you're walking a thin line. Let's hope someone keeps him in check, as they did with his previous games.
