That isn't how that sort of thinking is ever used in politics. If politicians start using language of "you've got to pick a side on this one!" it usually hints they're about to do something stupid. Occasionally evil.

The world is just too large and complicated for anything to ever boil down to just two sides. We can pretend it does for rhetorical purposes because otherwise political conversation gets hard; but it is important to leave space for the large group of neutrals who in all honesty probably have accurate interpretations of any given issue.

The truth is often close to one side or the other. Believing that is never the case is radical centrism, and leads to the absurdity where one can't decide between siding with the Jews or with the Nazis. I'd hope everyone sides with the Jews in that particular conflict, which isn't the same as saying they have to agree with every single thing every Jewish person ever does.
