Where I draw the line on 'free speech' is in the malicious libel or slander that uses lies or untruths to call a persons character or reputation into question and thereby violates that person's rights. But there are laws against that, and legal recourse. And nobody should be allowed to exercise his/her right to free speech to the point that he disturbs the general peace and becomes a nuisance, but there are also sensible laws against that.
And I draw the line on physically and/or materially hurting people for no other reason than they hold an opinion with which we disagree.
In this context, I am campaigning for a change in the law, or at least our culture, to make it illegal or unacceptable for an angry mob or group to organize and intentionally try to harm or punish somebody, physically and/or materially, for no other offense than that person holds a politically incorrect view or says something 'offensive'. Yes, boycott or protest those who are violating the rights of others. But so long as he/she requires no contribution or participation by any other, every U.S. citizen should be free to be who and what they are and say what they think, believe, want, and hope for without fear that some angry group will descend on them and pummel them for that.
If we are not free to be who and what we are, so long as we do not violate anybody else's rights, we have no freedom at all. We are subject either to an overly authoritarian government or we are subject to mob rule.
