Most of the people I know are non-Muslim. Nearly all of the people I consider friends, work with, study with, drink with, party with, or have slept with, are non-Muslim.
There is no discernible difference in hygiene. None whatsoever. The only thing close to a discernible difference is the fact that non-Muslims tend to not be disturbingly obsessive about which hand they use, or what magic spell they mutter before they enter a restroom, or whatever unnecessary oddball quirks your argument hinges on.
There is also a massive variance from Muslim to Muslim too. Not all Muslims are as OCD about cleanliness as you seem to be. It may come as a surprise to you, but many of them do actually lead normal lives.
Ishina, the point I was trying to make is that Islam emphasizes on hygiene and cleanliness as if it's a direct command from God, and that's quite effective, regardless of whether it's true or not.
Secondly, just because certain people are obsess with personal hygiene do not turn them into abnormal OCD zombies. There are many forums out there, Western one, that discuss about how to keep personal hygiene at its best. You made it sound like majority people do not care about it, at least, that's the implication that I understood from your replies in this thread.
Billy maybe quite right about my prejudice, I admit that, probably due to my previous Islamic upbringing that tend to view people who belong outside the Islamic circle as not clean. What did you expect when I personally observe Hindus or Buddhists who slight cleanliness in their routine life. A vegan who witness dog being eaten may feel the same.
Let say I am a bit careful when travelled to Korea or China due to the habit of dog eating there, that does not mean I belittle or disrespect the locals. You Ishina probably will never eat in a restaurant that you know that sell dog meat. Thus, you cannot blame me for highlighting one positive aspect of Muslims even at the cost of, as Billy said, prejudice against Non-Muslims.
