Yep, that’s blood.
UPDATE: Robert Spencer responds…
Blogwrath refers to “Arab bullies,” but the reason why they are so frenzied in their hatred of Jews is not, of course, because they are Arabs. There are Christian Arabs who live peacefully in Israel — and are joining the IDF in increasing numbers. The reason why they hate Jews with such undisguised bloodlust is because they are Muslims, and read in their holy book that Jews are their worst enemies (Qur’an 5:82) and accursed of Allah (9:30) — indeed, they’re the most vile of created beings (Qur’an 98:6)
