The fact that those laws were even on the books is in itself notable given that, again, anti-Semitism had largely been endorsed by previous governments.

And it wasn't just Germany either. Remember the Dreyfus Affair? That was in France pre-WWI. Dreyfus was framed by the authorities for a crime he did not commit, and initially got a life sentence before widespread public opposition led to a reopening of the case and ultimately to his exoneration. This whole ruckus shows that the very idea that anti-Semitism was something that should be opposed could be considered radical and anti-authoritarian at the time even in "civilized, developed" La Belle Époque France, never mind Germany! The mindset was wildly different from what we'd expect today.
