Your comparison with ethnic Poles is probably correct, although I don't know if they have a law of return. I not only do not have a problem with Israel, I fully support Israel and its valiant fight for survival; I wish them every success. I think its a great refuge for all Jews who are persecuted in other countries for the sake of their ethnicity. However, Israel is a foreign country to us, with its own interests, and they don't always coincide with U.S. national interests.
Again you are writing about Israel when supposedly your issue is with American Jews.
The Law of return is similar to getting points for civil service if you are a veteran.
Israel being the national home of the Jews (or maybe you would understand it better if we called the religion Judaism and the Nation Hebrews or Israelites) makes it easier for Jews/Hebrews/Israelites to immigrate and become Israeli citizens whether or not they are practicing Judaism (the religion).
Americans Jews who have not moved to Israel manifest a desire to be only Americans. They are not dual citizens and their status should be- in the absence of anti Semitism- like every single other American who chooses not to move to live in a foreign country.
