Why celebrate?

Sigh. Commentator Rod Liddle in the Times of London thinks the public display of Alison Lapper Pregnant is about "the fashion for disability," which he considers a "delusional ideology," and asks, "Why would we wish to pay tribute to disability; if we're being honest, isn't disability bad, wouldn't we rather not have it at all?" The argument sounds very undergraduate. So let's walk him through it like an undergraduate, shall we? This argument is the same as saying that we shouldn't celebrate any minority experience, because it's just so much easier and more pleasant to be a member of the majority. Why celebrate being a woman? It's clearly so much more noble and exciting to be a man like, say, Admiral Nelson (whose Trafalgar Square statue is fine with Liddle--he lost the limb and eye in battle, so that's indisputably tribute-worthy).
