The Muslim Brotherhood sounds like a fictional name a scriptwriter would give to a radical terrorist group. Its actual members don’t really fit that cartoonish characterization. They come across as civic-minded people of faith. There is none of the proselytizing or the menacing tones of hard-core Salafists — the Al Qaeda  types. The Brotherhood might well have a more radical agenda than their public face suggested after the demonstrations began, but on that occasion you saw them out with neighborhood groups sweeping the streets and directing traffic.
