It’s possible that they are silent because they are afraid.
Groups like the Anti-Defamation League and the American Jewish Committee have multi-million dollar budgets and they prize their access to the White House and the State Department.
Their leadership may fear that by objecting to anti-Israel discrimination, they will stop getting invited to White House Hanukka parties or that they themselves will become the targets of unjustified Federal investigations.
Perhaps it is fear. But perhaps they are silent because they share the goal of silencing voices that refuse to accept the Obama administration’s assertion that it is pro-Israel to support the establishment of a Palestinian terror state in Israel’s capital and in its historic and strategic heartland.
Perhaps they wish to muzzle Jews who refuse to accept that it is pro-Israel to be anti-Israel.Welcome to "sha, shtill," 2013 edition.
