On Aardvarchaeology, Martin Rundkvist tells the story of a 14-year old Swedish Muslim girl who also happens to be very good at karate. Recently this young woman was disqualified from a tournament because she wears a veil and the rules state "that the umpire needs to be able to watch for damage to each contestant’s throat." She was also disqualified from solo performance, despite that lack of potential for neck damage. Martin writes, "Things are changing in the karate world. You couldn’t compete wearing any kind of veil until last year. When it became allowed, Iran’s women’s team immediately won a world cup medal at kata – wearing regulation veils." Meanwhile, on Pharyngula, PZ Myers takes a few stabs at 'ludicrous' assumptions, saying they lead to "absurdities like the paleo diet, in which it’s assumed that we should eat like cavemen, because evolution." And on Respectful Insolence, Orac calmly parries the ignorant fear-mongering of online activists fantasizing about cancer cells in vaccines.
