It depends. During the American civil war the Confederate side was full of jews like Judah Philip Benjamin. He even funded KKK later which was created by Albert Pike who was a 33rd degree freemason btw (the KKK had masonic-templar symbology itself).
But really the Union side also had lot of jews and freemasons (Abraham Lincoln for example). You have to be very schizo to really give a fuck about that. There are always jews and freemasons everywhere just like there always are people of any other ethnicity or religion everywhere too.
