I think we should kill anyone who isn't anglo-saxon ASAP. Given my German heritage on my father's side, I am exempt.
How about that for a response?
Seriously though, I think you have to put the information in context. I think this article says more about the constitution of the Muslim community than it does about the British nation. Muslims are a small minority, but they have a much more homogeneous approach to naming with a very strong religious connection.
Now, compare this to the much more disparate British population a a whole, that is much more susceptible to trends and fashion, with a much weaker religious bias. Names like Oliver, Joshua and Jack were definitely not popular a few years ago but now they are in the top four.
The 12% rise in the name Mohammed is not borne by a 12% rise in Islamic population or male Islamic births. Interestingly, perhaps its an indicator of the Muslim community feeling that they need to assert their identity and recognise their faith? Maybe its a response to the negative spotlight that has definitely been pointed at the community as a whole? Or how about an indicator of the polarisation of the Muslim community, a key goal of the Islamofascists?
