Is this kind of like, all elephants are mammals therefore all mammals are elephants? Not sure that is a correct statement or even an intelligent statement.
Not all Zionists are Jewish and not all Jewish people are Zionists, so your first statement, FF, is in the realm of being correct. However, I am sure that most Zionists are Jewish and I am equally sure that some (a few) Zionists are not Jewish. One is more a political stance and the other is not. The other is more hereditary and they can choose to be a Zionist or not. In today's age there are people that choose to convert to Judaism and they can also choose to support the State of Israel (Zionist) or not.
Further, supporting the State of Israel as an entity and supposedly a safe haven for the Jewish people that are left in this world, does not necessarily mean you support Bibi's political agenda.
Equating those 2 things is usually where most discussions fall apart!
