I’ve yet to see any such harsh treatments in teshuvos, not any more than the Jew tax that was all over Europe, ghettos, etc…
And where did the tzlach advocate for emancipation from the ghettos?
I asked you for a source, and my reason for asking was that I’m not aware of Germany being any worse for Jews than Poland, Russia, Ukraine, Lithuania, Hungary, or anywhere else in the times of the achronim.
