No, not the muslims thats where the left hand comes in.
I know the original poster meant his comment in sarcasm.
But I had a conversation about toilet paper with some muslim students while in grad school. We were discussing different ways to clean yourself before toilet paper was invented. It appears the people in the middle east used a handfull of dry dirt, or sand to do the job if water was not available, and water does tend to be rare in the desert. And yes, they used the left hand for this. In europe they used paper or large leaves. In america they used empty corn cobs or paper. Currently in europe, the bidet is preferred...which is water. I believe the same is preferred in the middle east by wealthier people.
The corn cob thing really stunned them.
My first cousin was a missionary doctor in India for a few years and went to an Indian dentist. It was only after the dentist was done that my cousin remembered that in that part of India where he was, natives used their left hand. Too late. He never saw the dentist even once wash his hands or even wear disposable gloves to work on his mouth. Lesson learned.
