Write to your MP. This is serious. The UK Government has told Geert Wilders to stay at home. He is not welcome on these shores. If you don't know who Geert Wilders is, have a look at the film "Fitna" on Wikileaks. It's a film which plonks passages from the Koran next to images of various nasty things (terrorism, murder etc). The implication being that doing nasty things can be justified using passages from said book.
That literally is all the film is. It's just verses copied verbatim from the Koran and next to those extracts, photos and video of horrors committed by various lunatic muslims.
The British government has basically bowed to pressure (presumably due to fear) and kept the film's maker, who is a member of the Dutch parliament, out of this country. That's all there is to it.
See the letter
http://www.geertwilders.nl/images/images/letter-denying-geert-wilders-entry-into-uk.pdf where they say they that his presence in the UK would "pose a genuine, present and sufficiently serious threat to one of the fundamental interests of society", to keep him out. And that "The Secretary of State is satisfied that your statements about Muslims and their beliefs, as expressed in your film Fitna and elsewhere, would threaten community harmony and therefore public security in the UK."
Write to your MP. I will be writing to mine tomorrow. Last time I wrote to him, he responded in full, therefore I fully intend to write again. I would urge anyone that reads this to ask their MP to raise the question of what grounds he was barred from this country on. Watch the film. See if you judge it offensive - and - even if it was (which it isn't) is that a good enough reason to bar a man from visiting a supposedly free country? How many gay bashing, hatred of nonbeliever inciting clerics does this country let in per week?
I'll say it one more time. Write to your MP.
