I understand the difference entirely. Now explain how an ethnic German, who adopted Judaism, can claim, on the basis of religion, that their homeland is somewhere they and their ancestors have never once stepped foot in?
You are unable to understand that the Jews of today have no connection to the Jews of 2000 years ago. You, the person who despises religion, does not connect that an ethnic group from Europe is using a religion as a driving force for the displacement, replacement and erasure of Palestinians. The people whose ancestors are in fact, in part, the Jews from 2000 years ago.
