Why is Clarence Thomas so angry?

In his book review (Nov 12, 2007) titled "Unforgiven," Jeffrey Toobin asks " Why is Clarence Thomas so angry?"

I would argue Thomas’s anger reflects his tortured state of mind as he daily confronts the suspicions of perjury he almost certainly committed in 1992 in order to attain his seat on the highest court.

Anita Hill's allegations have become increasingly credible. After fifteen years of utterly stable respectability there is no clinical scenario that permits the possibility that she was insane or demented by sexual passion as was Thomas's defense. Nor could she, a conservative, modest Republican, have been politically motivated when, five years prior to the nomination, she bitterly complained to a confidant about being sexually harassed at work. Furthermore, Toobin points out, others have come forward with similar allegations about him. The preponderance of the evidence, clinical knowledge, common sense, and public opinion all point to the credibility of Hill's accusation.

Do we lack the imagination to consider what it must have felt like to be enticed by Senator Danford and his partisan committee cohorts to commit perjury—for he was under oath when making his defense—so as to categorically deny any and all of Anita Hill's allegations? This after having been selected by the white Right Wing as a token, black conservative, and in an inexplicable short time chosen and led, like a sacrificial bull, into the blinding arena of a Supreme Court nomination battle. No wonder he described as a lynching!

Why is the likelihood that he lied under oath never openly considered by Toobin nor in the media? Is it because lying to Congress under oath equals perjury, and the presence of a perjurer on the Supreme Court simply boggles the collective mind?

I suspect it tortures Thomas daily as he furiously contemplates the unforgiving price that his high position has exacted from his conscience. The white elites that conspired to thrust him into the Court must be proud of themselves and his performance. Thomas and the American people are left to suffer the consequences.
