Delusion: A delusion is a false belief or opinion, especially one held in resistance to strong evidence against it.
The European Jews are a European people just like the Germans but they claim to be the descendants of the ancient Hebrews – which is such a bizarre claim for a European people to make – it is just as bizarre as the Chinese claiming to originate in Yemen! But today, there is DNA which has confirmed that the European Jews are 100% European and DNA is never wrong! But you will never find any of them wanting to give up that ridiculous claim of theirs despite what DNA is saying – because if they did, they will not know how to claim Palestine.
