This is a pet peve of mine right there. The misunderstanding of free speech. Free speech is an ideal, one that the founders of the US government believed in. The First amendment, is merely something that makes the government respect free speech. Free speech is not the first amendment and the first amendment is not free speech.
So your argument there is a straw-man. LordFailstrom obviously believes in free speech irrespective of government or first amendment, and thinks that EVERYONE should respect it, not just the government. Sure, there is no law forcing anyone but the government to respect it, but that doesn't mean one shouldn't respect it.
