For over 2000 years Islam has been in & around Europe (Moors in Spain) & has also been pushed back in the same way. Now, with the PC brigade & human rights like you say the dynamics has now changed & from a European's point of view this has become challenging & when governments claim to have some kind of multicultural utopia I do worry because it is plain to see all is not good. I do not think ethnic cleansing will & I hope will never happen in Europe again but some radicals on all sides of the fence could start a small war within a small nation be it between different ethnic origins or purely religious & maybe could spread, a little like what is going on in North Africa but not for the same reasons. Holy wars, civil wars & ethnic wars for 1000's of years have caused many innocent lives lost. where wars in Europe in the last 100 years have battled against fascism & to repel communism, now it seems to be all down to religion in the near & Middle East & the West's obsession with promoting democracy, but for some neutrals like me think it is about one thing & one thing only - Oil & soon to be the lack of it.
