This is a fact that the biggest enemies of the jewsish people were those of the mix blood/marriage. They resented the Jewish controlled political and financial entities of the German country. Unfortunately there was no loyalty in the German riech even for half jews during the final solution. Who do you think were the doctors, scientists and politicians who encouraged the ethnic cleansing and forced extermination of the undesirables, where many of those same ideas as to control the population came to the states. These are facts that the half blood jewsish people resentment after wwi were the people who voted in a democratical election to give Hitler his power. Also the nazi soldiers who worked in the extermination camps used the jewsish people to work in the gas chamber, crematoriums and ghettos to control the jewsish population.
