Extreme over-exaggeration in my opinion.

Actually, just because one critcices the way the law is made doesn’t mean they think it’s basic intention is wrong.

As of your slavery example: Forbidding slavery is one(good) thing. Saying „everbody having somebody work for them out of anything but total free will and not being able to prove it is doing forbidden slavery“ is something else. If i must work because i need to eat and pay rent, is that total free will? How can anyone prove that?

So sure, the wording is extremely important.
