I simply can't take the middle east seriously, **** em.
What DFU did was silly, but I'd like to vager that if you took at look at the far left communist party "enhedslisten" youth organisation's summercamp, you'd see all sorts of leftist mockery of the US, the Danish PM, the police, Tony Blair even the monarchy maybe.
My point is, these are private events with drunken youths, who do stupid things like every other drunk youth does. The only difference is, so it seems, that if you're right winger, you're not allowed to do stupid things at a private party.
And FYI, I do think the DFU is a little extreme, and their leader appears to be a complete jackass, but hey, that's a political youth organisation for ya, some are extreme right wingers, others are anarchist scum.
