Never mind the anti-Semitism. That's understandable. They had to choose between Jooos! and anti-Semitic Arab "refugeees," so they chose the latter, trusting in the self-hatred of assimilationist Jooos! who helped build the Labour party to ignore or rationalize the anti-Semitism as "anti-Zionism" or "solidarity with the Palestinians" until it will be too late. Useful idiots, Jooo!ish or otherwise, are a penny a pound after all.
Understandable, but intolerable. But that's just the cherry on top of the sh!t sundae of Labour die-hard socialism and globalism and opposition to Brexit, and the erosion of free speech and other vital civil rights.
80% of secular Jews support the Political Left - no matter how radical or anti-Semitic.
Did they name names or just talk about the problem in their ranks in general terms?
