Can a teacher be fired for expressing political views online? Can I bring harrassment carges against someone?

The question of whether you can be fired from a public school for expressing your political views off campus is a hot button topic right now, and the answer is not entirely clear.  For example, teachers ahve been fired for appearing on a swingers website with their spouses.  If you are working at a public school, my personal view is that such a firing would violate your constitutional rights.  If you are working for a private school, of course, there is no question of constitutional rights (except for the provision against slavery, the U.S. Constitution only deals with government action, not the actions of private citizens), although there may still be state statutes in Georgia which might protect you.  However, the woman who called you racist has the right to freedom of speech as well.  She has the right to accurately quote what you said and to express her opinion that it is racist and that you should be fired for it (although posting the notice on school doors might be trespass, and if she lied you might be able to sue her for defamation.)  The first amendment (again, assuming you work in a public school) gives you the right to express your opinion; it says nothing about "without fear of retribution" from a private citizen (as long as the means of "retribution" are legal.)   BTW, I assume your opinion is that "we" can't afford illegal immigrants, not "legals."
