Thanks to Mark, who writes in:

We caught the Council on American Islamic Relations (CAIR), Orlando chapter, selling radical Jihadist material (books by Sayyid Qutb, the father of modern day Jihad) at a CAIR recruiting event.

If that weren't enough, they were also selling hard core anti-Christian books to children. One book ("Let the Bible Speak") states, "Thus you saw the Bible spoke, do you still think it is His [God's] Bible? These words of blasphemy are written by some liar. May God burn his fingers which wrote falsely these words."
