I don't think you have the right to use inflammatory language
NOTE: NOT A TEACHER
(1) I have to be super careful, for I do not want the moderator to either close this
thread or move it to a members-only discussion mode (which prevents non-members
from reading this).
(2) Therefore, I shall only say that:
(a) You are correct: inflammatory speech is not covered by any "rights."
(i) The famous example, of course: one cannot yell "Fire!" in a crowded theater
if there is no fire.
(ii) One cannot report certain facts during a war.
(iii) It is illegal to say certain derogatory words about certain races, religions, etc.
(3) The bottom line (as we Americans like to say):
Even if the Constitution gives us the "right" to say certain things, there are
things that a normal person would never say, for the consequences could be
legal (taken to court), social (losing one's job), or even physical (getting punched
out). In the United States, as in every other country, people simply do not say
certain things in public -- if they know what is good for them. De facto free speech
is limited in every country. That's life.
P.S. On American and British newspaper websites, all comments are moderated
before being posted. And some American newspapers will not allow comment on
certain controversial topics. Why? Because they feel that some comments are
simply too inflammatory for the community to tolerate.
