Quite true, and this even carried over to the New World, where frog legs are a favorite in Cajun Louisiana as well. So as I observed, "frog" for the French is similar to "kraut" for the Germans, implying a fondness for sauerkraut, which does in fact feature in many German dishes. Or Limey for the Brits, which I believe refers to the limes once carried on ships of the Royal Navy to help prevent scurvy. There is absolutely nothing insulting or derogatory in any of these nicknames, any more than in calling a person from Oklahoma a Sooner.
True, not every Frenchman likes frog legs, nor every German saurkraut, so these are in a sense "stereotypes", but if that equates to racism, then so does the phrase "American as apple pie", since not all Americans like apple pie either.
There are indeed offensive racial slurs in the world, but the above are not among them. Those who try to portray every nickname as racist are not only engaging gratuitous Political Correctness, but also exhibiting their ignorance of both history and language.
