Unlike many (most?) Leftists, Avraham Burg is a genuine liberal. The right of refusal, in most circumstances, would be a nearly holy value for him. What I find interesting is that he still wears a kippah. He has reduced Judaism in his personal life to personal religion, with little concern for the public values of Judaism. He truly saddens me, because he does not bring honor to his father's legacy.
Maybe because he likely supports soldiers' refusing to serve in the shtachim, for instance?
