We live in an age of antiheros and victims. Christianty is a heroic ethos in which we are all called to be great saints and heaveen rejoices in the triumph of every soul. I find the celebration of the sinful and banal by media a lot more troubling than the painting.
And that's a problem in and of itself.
That painting is not a product of our time, and I find it very 'problematic'. The style is borrowed from Byzantine church art, in which God is placed in the center of all things (where He really is), and the Saints and Angels are placed around Him (where they really are). That painting puts NOTHING in the center, but places George Washington in the place of highest prominence. It seems to imply either that Nothing is god, or that George Washington is god. If you're looking for examples of apparent 'ancestor worship' or 'idolatry' in the form of worshipping mere men or anthropomorphised ideas, look no farther than Washington, DC.
