There are two considerations of his dilemna; Who is a Jew? and What is a Jew?Declarations of ethnic identity are more formalistic than substantive. Historically, the question of What is a Jew is of greater meaning than the first question. Other than my identity card certifying that I am a Jew according to Israeli law, what is my connection to Judaism. It is illogical historically, to assume that the current interpretations of what is a Jew-Reform, Conservative ,secular, pluralistic. Orthodox, et al are all legitimate because some of them are contradicory of the others. Those repeatedly declare Israel as a Jewish state really mean to maintain a Jewish majority. Is this what it is to be Jewish?Does the current population of the USA have the inherent right to redefine what it is to be an American?That right rests with the founding fathers of the American republic and so it is with the Jewish people.Even in sports if you change the rules of soccer it becomes rugby and if you alter the rules of baseball, you are playing softball, not baseball.
