The words democracy, socialism, freedom, patriotic, realistic, justice have each of them several different meanings which cannot be reconciled with one another. In the case of a word like democracy, not only is there no agreed definition, but the attempt to make one is resisted from all sides. - George Orwell, Politics and the English Language (http://www.mtholyoke.edu/acad/intrel/orwell46.htm)

This should be posted at the top of every political discussion, in my humble opinion.
