This England V France thing has been going on for years, I personally find it a light hearted jibe between two nations, much like that between the Brits and Auzzies.
I watched the finals, and saw the Tons play. They played great fast ball and deserved the win, unless their ability was assisted by illegal fire modes, which can neither be proved or disproved at this point.
The booing was for the Ton Tons as a team, not as French players. I was told this was due to their conduct over the weekend (which led to a few players getting banned). The bonusballing I saw bordered on the excessive, and I wouldn't want to be on the arse end of that, from any team/nationality/sex/religious beliefs/etc.
I think the French bashing on this forum is harmless. No-one has been over the top, the picture of the Crazy Frog was obviously meant as a joke, but if people took offence then I'm sure it will be removed.
At the end of the day, stick a bunch of players on a field in identical kit and who could tell me where any of them are from?
