Henry said that upon his execution, not during the context of any legal or diplomatic setting;. context is important.
And of course, 'liberty', "freedom', and so on in any civilized, 1st world country are not absolute, and for good reason.
A rapist does not have the "freedom" to rape women, nor a slave owner have the 'freedom' to own Africans as property, nor does one have a right to yell "fire" in a movie theater, and call it "free speech". Nor is there any right at all to 'riot' as opposed to peaceably assemble, and so on and so on.
The same with idiots who think that "free speech" mean that a private individual or employer doesn't have a 'right' or delegation' to decide its own rules within the limits of the law, regardless of what they want to argue about not respecting "free speech" in principle.
A private business, for example does indeed have a legal right to have a legal right to remove people at its own discretions and common sense, regardless of ultimately what one thinks about whether or not they "should" do it - sans a person proving it was done discriminatorily in a way recognized such by the law, such as racial. (For example, a business would have every right to personally decide to remove an individual for promoting Neo-Nazi propaganda, even if technically what they were doing was legally protected, as far as the law goes, the business would likewise have every right to not want to be associated with it, and would not be obligated by law to provide them a free platform to do so at their own expense).
Since the vast majority of these "free speech" arguments are predicated on complete legal ignorance or apathy on what "free speech" actually is, in practice, as far as the history of law and legal precedents and interpretations, and ultimately they could care less about the "constitution" to begin with, and would still be arguing for it simply because they "want to", Constitution or otherwise, since it's predicated on mob psychology and irrationality, rather than so much as having read a single book on the subject or care enough about it to to begin with.
