On the right to be wrong.

To have a right to do a thing is not at all the same as to be right in doing it.  ….. If a man has a right to vote, has he not the right to vote wrong?  If a man has the right to choose his wife, has he not the right to choose wrong?  I have a right to express the opinion which I am now setting down; but I should hesitate to make the controversial clam that this proves the opinion to be right.
