my family history is traceable back to the immigration into holland and later the dutch diaspora (zeeland and fleming) on my fathers side, my niece has a jewish father, my other niece's husband has polish jewish blood but are we jews?
and some of the jewish population in london is welcoming of a muslim mayor which indicates to me that they are either not really jewish and they have forgotten history or they are playing sides (same with hillary who is an ally of islam rather than israel)
