Knowing the atrocities and the genocide that the Nazis committed behind the cover of the law, and how their antisemitism was at the root of so many of their laws and actions, I would never agree with any of the laws the Nazis passed. I would be concerned that I would be validating, enabling, or endorsing the antisemitism that inspired any particular opinion or law.
For example, why did the Nazis pass a law strengthening protections for animals? Was it for moral and ethical concern of animals? Or was it so when they later dehumanized Jews that they had a legal framework describing how they could treat Jews like draft horses and lab rats, and protecting the Nazis who would conduct torturous experiments on them? The Nazi motivation for any action is corrupt and inseparable from their antisemitism and genocidal conduct. This is why the greyed out commenter above feels that the opinion of a Nazi sympathizer doesn't matter, because one can't tell whether or not their opinion is based on antisemitism and genocidal ideation or not.
Knowing that antisemitism is coming back into style, and seeing your agreement with this infamous Nazi's law, I'm finding your earlier denial of Naziism suspect. One cannot simply agree with a Nazi without casting suspicion upon oneself and one's motivations.
