Sounds like denial. Just because your parents are close to their white neighbors means that there are no racial and extremism problems that exist there?
I never stated that there weren't any racial or extremism problems. All I stated was that things are nowhere near as bad as you are making them out to be. The amount of opposition against EDL, the far right group politicizing the event, has met great opposition from a lot of people in the country.
US in general is a lot worst for Muslims than UK. People here are used to living with Muslims while the American population hasn't had the same amount of interaction. Although I would say that Americans are a lot more friendly and this is based on our interaction with American family friends.
Theres obviously something wrong with society in the UK since theres a big population that has tendencies towards extremism. I have talked to Britishers who have left the UK because according to them immigrants have turned it into a third world country. Just because you might live in a bubble, doesn't mean things are hunky dory there.
There is something wrong, especially with the Muslim population of Pakistani origin. This can be said for the Muslim population of North African descent from France, the Middle Easterners in Australia etc. Had America had a large influx of immigrants from a Muslim country a few decades ago, the same problems would apply there. This is not a country specific problem, but a minority specific problem.
As for those people who say its a third world country. They haven't even lived in one because UK is possibly the best welfare state in the world and attracts all and one from around the world. Free health service, free housing, tax credits, income support, it doesn't get better. Things are not the same due to the prevailing economic condition but its still a very stable place.
The people you might have spoken to are clearly anti-immigration. I would suggest you revisit this country and travel with a different set of group, not your typical anti-western depressed Asian group.
