They don't invade and occupy by choice? Or is it because they can't? Saddam Hussein had a very good go at occupying Kuwait did he not? Your telling me you think if Muslim countries had the power to occupy Israel and Europe they wouldn't?
Also you say Muslim countries, I didn't mention them once in my post so it's interesting you mention them? But while we are on the subject you mention Britain doesn't have a culture? I think it does, and it is one of the best on the planet when it comes to equality and freedoms. A prime example of a culture clash would be when a new worker at my job refused to shake the hands of my boss because she is female, to me that is discrimination by definition, and a huge mark of disrespect, but nothing was said because it's his religion!? Additionally my sister works at a builders merchant near burnley, the majority of Muslim men who come into the shop flat out refuse to be served by her despite her being a manager.
This is what I'm referring to when I say culture clash, and yes your right there are different interpretations of British culture, but if my definition means I won't shake a woman's hand I'm branded a misogynist, but if a Muslim does this it's okay?
If I go to Saudi Arabia with a woman and she wears a dress in public, or isn't accompanied by me she won't be let off because she's British,but we allow them to keep there culture, which is fine, unless it goes directly against the equality and freedoms that make our culture one of the best.
As I said some of the hardest workers and nicest people I've met have been migrants (including Muslims) but bringing in large quantities when there aren't the facilities to accommodate them leads to segregation not integration which is the problem.
I'm all for migration, when we can accommodate it and also when it's done methodically for the improvement of our country, which is a point that is hard to disagree with no?
Also your last point about our responsibility, I along with a large majority of people disagreed with the occupation in Iraq and Afghanistan, it was our government, not our culture that occupied. Lumping British culture in with the military generals who carry out drone strikes and occupy countries is like comparing all Muslim countries with Isis, how much say did the people have to prevent the occupation of Iraq? Zero, so no I don't think British people as a whole owes anything to other countries. (Just a disclaimer I fully support our troops, our military is filled with men and woman who basically said to our government here is my life, use it to protect our people, unfortunately politicians priorities are ****ed up, but that doesn't take anything away from our armed forces as individual people)
