Oh, Anne.
In only one way are those people correct.
It IS full of Muslims - in that single respect they have it right. Turkey has the highest rate of Muslim population in the world - more than any other country.
However, the vast majority are like you and me.
We want the same things; we think the same way, we get on with our neighbours and help each other when we can.
We/they are neither dirty nor terrorists.
Those people you cite are ignorant.
