"Of the Western monotheist tradition," maybe. I guess I don't have much of a problem with "Judeo-Christian." I have never heard the complaint you mention, that it implies Judaism is a subset of Christianity. It seems more likely to me that it was simply an easier verbal construction than "Christo-Jewish." Merriam-Webster puts the term's introduction at 1899 and defines it simply as "having historical roots in both Judaism and Christianity," so in my opinion anyone who would apply much deeper meaning to it is not on very good footing.
