the language of the law is so amazingly vague
Vague laws & variable enforcement = pathway to tyranny.
You can be arrested for even being suspected of having illegal gun parts - high-capacity magazines, silencers & fittings, automatic sears (yes, Citizen, a cube of metal 1/2" on the side can equal 5 years in jail...), even rubber O-rings that can be qualified as being "potential parts of grenade launcher attachments". Vague definition = arrest, fine, jail time, and a ruined life... for a piece of metal or an O-ring.
Meanwhile, David Gregory can wave around a highly illegal high-capacity magazine on public TV, and the DA will "decline to prosecute". Because the law that will land YOU in jail doesn't apply to the Ruling Class. Variable enforcement = some people are above the law.
It wasn't necessarily that the information was misleading, but that it would lead patients to make decisions about their own care without necessarily consulting a doctor, which the FDA thinks is not a good idea -- and I totally see their point, frankly.
So, by the same logic, let's shut down:
Oh noes! Medical information out in the open! How dare those peasants make decisions for themselves! We must protect them from themselves!
Yeah, let's deny information (however flawed it may be, it's better than nothing) to people with a capacity for independent thought, for the sake of coddling & protecting the morons.
