Edinburgh Dungeon breaches anti-discrimination laws?

News that Edinburgh Dungeon is refusing access to English people, unless they sign an oath of allegiance to Scotland, raises questions about whether the museum is breaching European anti-discrimination laws.

According to the Telegraph: The Edinburgh Dungeon said the one-day event is in revenge for the Battle of Falkirk, fought 710 years ago July 21st, at which more than 2,000 Scots were slaughtered by the Auld Enemy. English visitors will only be allowed entry if they sign a scroll swearing allegiance to Scotland, while those from other countries will be encouraged to bring in items deemed 'typically English’ to be smashed.

So not only are they being deliberately offensive to people who had nothing to do with a battle 700 years ago, they are simply destoying 'English' items for the sake of it. In an age of when we are all encouraged to recycle and minimise our use of natural resources and minimise our waste output, this can only be seen as grossly irresponsible. Not fun, just wasteful.

What would have happened if they had said that black people weren't allowed into the museum unless they swore an oath of allegiance to white people?

Obviously it is a one day event, and this whole thing is just a publicity stunt. However, such xenophobic nonsense is hardly condusive to better relations.

Update:
According to the Campaign for an English Parliament site, the Commission for Racial Equality has made a complaint and the police have also been involved.

Update 2:
Looks like there were lot of complaints!
