I didn't notice it on the internet before Freedom Fries. Yes general dislike of the French is typical in the Anglosphere because of historical reasons and rivalry. But people don't see it as such. A similar phenomena is Eastern European nationalism (you know the type of Polish/Moldavian/Russian poster I'm talking about), with the difference that the nations in question have fever trolls on their side and get mocked as much as they should. Americans don't.
