You and your associate terrorism with being a Muslim

No-one has.
Only with being an Islamist, which if you have been following recent events is regarded currently as the greatest terror threat by far.

Survey show that Muslims, of all immigrants, are prepared to settle in Britain and be recognised as British,

That is good, but what surveys?
We know from MI5 and Anti-Terror Police that there are thousands of them here who regard the public as legitimate targets to attack and kill.
That may be a small proportion, but you seem to be denying it.
