Richard Silverstein says that J Street might as well join AIPAC:
I’d never quite thought of the fact that J Street either intentionally or unintentionally may serve to co-opt the political energy of the American Jewish peace movement. Progressives funnel their energy into the organization which transmutes it in turn into faintly liberal pro-Israel substance that bears only a slight resemblance to the actual political values of many of those progressives. In this way, J Street contributes to the dumbing down of progressive Jewish politics.
