Anglo-American in Paris

This photo shows a very small sign (it is almost life-size) that I saw in Paris this Monday. The sign says (if you ne parlez pas):

There are more signs in Anglo-American around Paris now, than there were in German during the Nazi occupation. It would suffice if French-speaking people just revolt against the decision-makers. I am of the people, and my language is of the poor people.

and the sign is signed Michel Serres, philosopher, academician, historian of science at Stanford University (USA).

irony.
