Naming your kid after their disability

From Andrew Sullivan, who obsesses about Sarah Palin but does it in an interesting and readable fashion, about her infant son Trig, who has an extra chromosome 21:

The medical term for Down Syndrome is Trisomy-21 or Trisomy-g. It is often shortened in medical slang to Tri-g.

So Sarah Palin seems to have named her Down Syndrome kid after a slang term for "Down Syndrome."

I just wrote that I could imagine what people who have kids with a variety of handicaps might name them, but after a flash of adolescent giggling, I saw they were all in really bad taste, so I deleted them. I'm not the most PC person in the world, but even I could see I was going too far.
