Tell that to the Vendeeans, Professor Gay.
Wherever theological intolerance is admitted, it must inevitably have some civil effect; and as soon as it has such an effect, the Sovereign is no longer Sovereign even in the temporal sphere: thenceforce priests are the real masters, and kings only their ministers. Now that there is and can be no longer an exclusive national religion, tolerance should be given to all religions that tolerate others, so long as their dogmas contain nothing contrary to the duties of citizenship. But whoever dares to say: Outside the Church is no salvation, ought to be driven from the State, unless the State is the Church, and the prince the pontiff. Such a dogma is good only in a theocratic government; in any other, it is fatal.
-Rousseau's Civil Religion
Tolerance is nothing new. Only the parties have switched places.
