The problem with your theory is that none of the people I know are antisemitic, or dismiss the injustices Jewish people have and continue to experience. You can oppose the Israeli Occupation which displaced Palestinians and still respect and fight for the rights of Jewish people. Indeed, we must understand that this wholesale slaughter of Palestinians for retribution is injustice personified. Just as I would oppose a Nazi, so would I oppose any regime that segregates, humiliates, and dehumanizes people based on race, religion, gender, or any other facet of identity.
