Now if you want to talk about prayer beads, all those guys are heavy into idolotry.
That is not why I consider moslems mohammed-worshippers. Actually, I think pbuh is a rather gracious and even endearing mannerism. It is not to my taste, because it is repetitive, but I understand the sense of true respect and honor behind it. I have no problem with it.
What I have a problem with is the regard of mohammed as The Perfect Man, an absurdity carried to violent and mindless extremes. What difference is there between bowing down five times a day, and rioting and murdering because of pictures? The intensity of feeling and thinking is impossible to distinguish, in terms of adoration.
