Well, I should point out that religious intolerance isn't racism, so I'm not sure why they are calling it that. They also seem to be playing up the importance of the party in Danish politics from what I can tell. Almighty wiki says they only get 13.5% of the vote and have one member in the European Parliment.
Mind you, their rhetoric is pretty darned extreme and I'm surprised they get even 13.5% of the vote, but I can't see how that translates into 'the most influential party of the last decade' by any stretch of the imagination.
I'm leery of having an American President speaking critically of a political party internal to a US ally, though. For one thing, it might just have the opposite effect that the makers of the video are hoping for. I know I wouldn't take kindly to any European chief executive sticking their nose into internal American politics, and the Danes may well feel the same way.
Oh, and honestly, I would have preferred it in written format. Irritating to watch it on Youtube with scrolling text, and the background music is irritating as hell.
