oh, by the way
In playing devil's advocate in this argument I am going to be wilfully blind to the original poster's claim that islam is simple because it doesn't have the complication of a 'powered holy cross'.
Islam may not have a 'powered holy cross' but it suffers from no shortage of 'the weird and wonderful'.
To find examples of this you need to do no more than google the claims made about the kaaba in mecca, its black stone and various other holy places or holy objects that any serious practicing muslim ascribes supernatural importance to.
Some people take this superstition to truly ridiculous heights, such as in the second part of this video on utube

the part I'm talking about starts at 05:25 in the video.
The first five minutes of the video are irrelevant to the point I'm making, but they're entertaining, although tragic.
