Disturbing, but given the recent additions to the court, not totally unexpected. I'm a bit surprised that they've leaped so soon to replacing rational legal argument with ad hominem attacks and pure invective, but I knew Kagan and the Wide Latina would steer the court in an ugly direction, given half a chance.
They are not jurists - at least not of the type we as Americans expect. They are apparatchiks, in the original Soviet meaning of the word.
