Jaanvi, i do not think ANY Muslim would ever openly say that for fear of being killed for doing that kind of thing.

Now, tell me this...are there Muslims in Europe who do not have an ounce of respect for the religion that is common there?
Let me answer you...YES, there are.
So, I think disrespect exists everywhere.
BUT, saying one does not want to be Muslim is, IMHO, not disrespecting Islam, as much as not wanting to be Christian,Jew, Hindu, Shia etc. is disrespecting those religions.
And I also do not see anything wrong with saying that either.

Besides, what has working in Qatar to do with not wanting to be Muslim??? I don't remember that being mandatory to work here.
