re: Can anyone explain Alabama fans’ infatuation with using French heritage as an insult?

No we hate the French b/c of 2 world wars, playing a role of pulling the U.S. into Vietnam, backing out of NATO because they knew we’d take care of them, then selling weapons to our adversaries… many of which were used against the Brits in the Falklands war. They’re assholes as a standard. I can say this with absolute certainty having worked with French citizens.
