If we believe that we have a right to free speech, then we must exercise it occasionally, or we will lose it.
If we have freedom of conscience, then we must occasionally think "bad thoughts", or we will lose that freedom.
If we live in a free society, we must also grant these rights to others.
If someone exercises their free speech rights within my hearing, and does me no explicit violence, then I get to exercise my right NOT TO BE OFFENDED in order to keep the peace!
Of course, if I do not have a right not to be offended, then I probably have no rights, or sense, at all.
