Well, again, since the feds are absolutely limited by the Constitution which is the ONLY source of federal power to act, the first and really only question you have to ask yourself about the feds is, “Is it constitutional?”.
I see nothing in the Constitution to authorize the feds to interfere with our food or drugs or to establish the FDA. “Ensuring safety and security” is not an enumerated power delegated to the feds by the Constitution and ONLY enumerated powers are those the feds may exercise. Since unconstitutional federal acts are by definition acts of tyranny, the FDA and its activities are acts of tyranny.
Are you a constitutional scholar?
