It sounds like you're saying that if there are any consequences for speech then it isn't free. This probably isn't what you really mean so please feel free to clarify your argument. I'd rather debate your real position than rip apart a strawman.
You're correct that all you said was that free speech and the first amendment aren't the same thing. The statement that you replied to indicated that a response to your speech was not limiting your freedom of speech. I read your response as disagreeing with this statement as well as pointing out the difference between the first amendment and the broader concept of free speech. Did I misinterpret what you wrote?
