Unless the Skin Heads and the Football hooligans start killing Muslims in huge numbers I don’t see any other outcome as likely.
So in a word yes.
96% of the UK is NOT Muslim. The UK Muslim birth rate is/will be dropping. For all the noise, Muslims don’t have any major political, social or economic power.
Does the UK have a Muslim problem?. Very much so, and one we have been and need to sort out, but ideas of a conquest are nonsense.
