They are largely missing the point. Roberts is really O'Conner's replacement and he is less certain on abortion. Alito is really Rehnquist's replacement and it was totally sppropriate to replace Rehnquist with a strong conservative.
I am not convinced that this is as large of a win as it could be.
You may very well be correct but don't give the whiners the satisfaction of hearing it. It's nice to hear them squeal.
