It's not the being concerned about figures that's the problem, it's what you're doing with the figures that is.
Remember this thread is about ISIS, an organisation thousands of miles away in the middle east, yet you bring up figures about people here, complain about multiculturalism and generally hijack a thread about an incident that is completely unrelated to the vast majority of people here, except of course, they have the same religion...
How many people have gone to the ME to fight for ISIS? About 100 at the last count IIRC. There are millions of Muslims in this country... Just because they don't all jump up and down screaming about it doesn't mean they condone it. The "with us or against us" argument is used far too often by those intent on stirring up trouble (I offer Godwin here again as an example... Again, I'm not calling you a Nazi, however I am pointing out the similarities between their argument against the Jews and your arguments in this thread).
The fact members of a group would like a political party to represent their views isn't shocking, it's standard political fare, whether they be rich people, poor people, Christians or trade unions.
As for killing in the name of religion, how many of the non Muslims were religious? What was the context of the question? What were the replies of non Muslims when divided out into religion? (I ask some of these questions again because you didn't answer them before) what would be the reply when asking a group of another religion?
There is an agenda here from you and several others in the thread and those statistics are being used to further it. That agenda has nothing to do with the killings of a group in the ME...
edit. Majority of Central London knife crime is comitted by black people. <- does that make me a racist?
No, but it would if you then said that back people were dangerous...
