I am sure many 'normal' practices in the US would seem bizarre to Muslims. Cultures differ and I think we should respect other cultures. I am sure it would look strange to them that people put trees in their houses in December, put lights all around it, and then tell children that some fat person in a red suit with a sled and reindeer comes down the chimney and delivers presents. It would seem strange to them that we sit on a toilet rather than the more natural, easier method of squatting.
The only problem that I have with Islam is the imperative to spread it around.
