I am afraid they are here to cause a lot of agony and suffering, they are here to stay and this country only has itself to blame! Why do we keep welcoming these C**TS in with open arms??
The problem is that largely these are not "c**ts" we are letting in. The majority of the time they are homegrown "c**ts", from families which were not disposed to terrorism when they arrived. As for who we let in, there is an argument to discriminate against a particular group on the grounds that a very few of them are a threat to us, but that argument is extremely weak at best. I don't remember much of the equivalent argument being applied to the supposed benefits of driving the Irish out, indeed there wasn't even a real border with the mainland.
Southern points out that usually the people responsible were "known to the police" or security services. I agree with this, but vast numbers of people, if not everyone are known to the police/security services. It's a meaningless phrase (all gun owners are, for example). The fact is that what is known to them is not sufficient to give suspicion that they actually intend any sort of attack. What is usually presented afterwards as evidence in hindsight, is rather like saying that Fred watched the film Heat which is evidence he was planning an armed robbery.
Notwithstanding the above wishy-washiness, I see no particular reason for any human rights to extend to anybody found to have indicated allegiance to a jihadist organisation or cause. A series of accidents seems in order. The problem is that whatever rule or limit you set, these people will circumvent it.
Perhaps we should be rethinking how and whether we afford Islam the status of being a religion - because in important regards, it isn't. The word religion as Western people understand it doesn't adequately describe it. It is religion + nationality + statehood, patriotism, law and complete subjugation to those. We'd be closer if we thought of it as a combination of religion (belief) and fanatical Nazism/communism (means) working towards the eventual establishment of Islam as the religion of everyone surviving on earth (end). Now most Muslims have the good sense not to pay too much attention to this aspect of it, in much the same way as most Christians ignore chunks of their religion which seem out of place.
Also, there is a very widespread problem among the wider, innocent Muslim community. There is a serious problem with where they get their news/ facts from. A recent study showed that more British Muslims think that 9/11 was done by Jews than think it was done by Muslims, and plenty of other obviously completely bonkers stuff. As a group they need to make it entirely clear how harmful and wrong much of this stuff is and to reject it, because this is where people get the sense of grievance, outrage and total lack of perspective that to them justifies them going and doing stupid and evil stuff. I'd defy anyone who accepts the sort of c**p widely asserted to be fact in those communities to have reasonable humane attitudes.
The problem is the intellectual space given for extremism to thrive. There are far too many people sitting too close to the fence making excuses, failing to condemn, making political points which lend space for jihad to start looking acceptable. The same thing happened with the IRA, there were plenty of Irish people, British lefties, Americans with chips on their shoulders all willing to provide excuses for their behaviour, failing to distinguish it as terrorism, blaming the other side and so on. In fact there are people on this site like that. Ridiculously, they're probably outraged at this bombing too.
Some Muslims are never going to accept our values, because they oppose their beliefs in reasonable areas. Some Christians have the same issue. It's not a problem except where it combines with
