I don't see what your point is. Maybe Alito is privately pro-choice (as Kennedy is pro-life) but no one cares about that. It's his legal opinion that counts, and Alito's dissent certainly was anti-abortion in that it found certain prohibitions on it acceptable. Certain prohibitions, I might add, which are going to be a PR nightmare (a wife must notify her husband beforehand).
My point is that you cannot infer anything about Alito's personal views on abortion from his decision in the case. Nor was his decision "anti-abortion," as CNN described it. It simply was a finding that the husband-notification statute was not unconstitutional.
There could be another case in which Alito would have ruled on the other side. Would that make him "pro-abortion"?
