Free Republic is not about you "calling the anti-Semites as you see them." I don't care why he posted anything. If his posts are anti-Semitic, feel free to call him on that. That's relevant. Your concern about his motivation on non-anti-semitic posts is not.
Making every thread one about your past struggles against Larry's anti-semitism is narcissistic and stupid. You say, "Larry posted it only becuase she is Jewish." I might add that you only seem to care because she's Jewish.
