Ms. Torkelson has a quite interesting repertoire of articles.
I suggest she do a comparative study of all other religions from Ahura-Mazadism to Wiccan and Zoroastrianism and she if she find a single one which advocates converting other people by violence and force and killing people who don't their follow religious tenets.
My suspicion is the only one she will find is Islam. Although some individual Muslims will deny it, present widespread practise, the example of their founder Mohammad, and their own religious texts prove otherwise.
Spot on.
