Unseemly demands and bizarre notions

I'm glad to see that Andrew Sullivan now says that he will stop pressing for Elena Kagan to say whether she is homosexual.  He continues to insist, however, that his demand that she do so is perfectly legitimate. I don't get it.  It is difficult for me to think of a less appropriate or more unseemly demand.  Am I missing something?  Solicitor General Kagan has done nothing to make her private feelings or romantic interests a public issue.  Could we please keep the focus on Kagan's abilities and achievements, record, temperament, and judicial philosophy?  Sullivan's conduct calls to mind his bizarre crusade during the last presidential campaign to raise doubts in the public mind about whether Trig Palin was in fact Sarah Palin's child.  His suggestion was that the baby was the child of Palin's eldest daughter.  I couldn't fathom that one either.
