Good Grief!
If I took seriously every claim on what I should be ashamed of, then I would have to be ashamed of being white, well-educated, male, straight, employed, affluent, a military veteran, married to an Asian woman, living in a nice neighborhood, and driving a foreign-made car.
I refuse to be ashamed of any of these things, and I really don't care what some classist, racist, sexist goober-brain says to the contrary.
... and I mean that in the nicest way possible.
