A contentious debate over Judaism's relationship with 1960s New Left activism played out through a series of critical letters responding to Robert Saks' "Jews, Judaism, and the New Left." Through analysis of correspondence from Richard Arenberg, Herman L. Horowitz, and Allen Rutchik, along with Saks' rejoinder, fundamental disagreements emerged about whether Jewish religious tradition could align with New Left principles. Arenberg challenged Jewish leadership to engage in serious self-examination rather than simply trying to reclaim "stray Jews," suggesting the New Left's moral framework might offer greater truth than established institutional positions. In contrast, Horowitz condemned the movement as misanthropic, arguing that its shift from civil rights to Vietnam War protests revealed a disregard for actual human welfare despite rhetorical commitments to human values. Rutchik highlighted the central tension between particularistic religious ideology and the New Left's internationalized identity. The exchanges illuminated broader generational conflicts between religious institutions and youth activism, leaving unresolved whether accommodation or separation better addressed New Left critiques of contemporary Jewish positions on social justice.
