150 thousand germans for gay rights

I notice in the film A Look Into the past it says that 150,000 Germans were in favour of gay rights and that Albert Einstein was one of them. I wonder why it is the Germans were not utilized as a League Of Nations force against Adolph Hitler and The Nazis. The League of Nations was set up after World War 1 to stop further wars.


I note also that a German war veteran named Gerber came to Chicago in the 1920's to the U.S.A. to set up a gay rights organization and was arrested. I wonder is this the same man who formed the Gerber Baby Food Brand.
