It's idiotic.
As I said, I can post a link which "proves", if proof is to be so flimsily made, that all liberals are mentally ill. I can post a link which "proves" that women are 10 i.q. points lower than men. I can post a link which "proves" that we start life as star sparkles in outerspace.
If my standards were as low as the left's, that is.
Which they aren't.
But just for hyucks and giggles:
"Democrat or just demented?
... Early this summer, Senator Bill Frist, the first practicing physician elected to the Senate since 1928, plans to file a bill that would define "political paranoia" as a mental disorder, paving the way for individuals who suffer from paranoid delusions regarding voter fraud, political persecution and FBI surveillance to receive Medicare reimbursement for any psychiatric treatment they receive."

You're just mentally ill. You can't help it. And there's my proof that it's so.
