However, if you're going to defend Islam, do it right.
For example, there's the way Ms Armstrong defends what Muhammad did after the Battle of the Trench -- namely, the execution of the seven to nind hundred Banu Qurayza combatants, who were going to let the Meccans into Medina so they could slaughter the Muslims. The problem is, this so-called "massacre" never happened.
The proof that the massacre is a legend has been out there since 1976, when W.N. Arafat published his article "New Light on the story of Banu Qurayza and the Jews of Medina," in a historical scholarly journal. (Today, you can find the entire article through your favorite search engine.) Since Ms Armstrong didn't bother to find it with hers, she only gets four stars here.
