... according to the CIA Factbook.

This means, of course, that all Turks who are not registered as non-muslim are classified as muslim.

I read somewhere that non-religious Turks in Germany complain that they are officially referred to as muslims because they come from Turkey

Only 77% of Americans are Christian.

I could easily imagine that, Turkish people and islam are strongly associated here, since also most German muslims by far (with exception of some people from former Yugoslavia and the Soviet Union) or their families are of turkish origin.

No, it's more like "anything that might be water must also be an ice cube".
