Kagan, Breyer, and Ginsburg are Jewish, all of the rest of the Supreme Court Justices are Catholic.
The problem for the Jewish brand is that all 3 of the Jewish justices are hostile to White interests. It is practically a certainty that all will vote against the Arizona law when the case comes up, with the possible exception of Kagan recusing herself due to conflict of interest, since she was the Solicitor General on the case in the first place. If a 4-4 tie didn't have the same net effect as 5-4 against (since to overturn the previous court requires a majority), I doubt very seriously whether Kagan would recuse herself despite the blatancy of her conflict of interest. Sotomayer will also almost certainly vote against the law. In all likelihood, the decision will hinge on the vote of Kennedy.
Now, when things fall apart and the center does not hold, just WHO do you think is going to have absorbed the blame here? It doesn't matter who writes the majority or prevailing opinion, or who concurs in part. What matters is the end result and whether it tars the Jewish brand further. Breyer and Ginsburg have long been hated by many. Kagan creates the possibility of creating decisions that inspire vitriolic hatred on the back of a majority Jewish vote (3 Jews and 2 Catholics). Who do you think will be blamed here? Do you think this will inspire a pogrom against Catholics? No, they'll be swept under the rug, and the fact that 4 Catholics voted on the side of 'righteousness' will be considered instead. There are presently several really significant issues on the Supreme Court's docket, issues that I guarantee will create lots more anti semites if they go the wrong way and might even if they go the correct way. The fact that all 3 votes can be predicted with a great deal of certainty in advance without even so much as a law degree by a layman is also very concerning.
Ginsburg and Breyer are both pretty old (born in 1933 and 1938 respectively). I'd suggest that when the time comes to replace them, that Jewish folks back a Jewish justice somewhere to the right of Justice Thomas for one seat and a white Protestant for the other. Holding a block of 3 seats in the SC is an extremely dangerous lightning rod. It's not in your interest to have the average Joe in the US think of those 3 when he thinks 'Jew'.
