Well, they might be, but seeing that they deny the Crucifixion and Resurrection (Mohammed seems to have based his account of Jesus' (or Issa's) life on the gnostic 'Gospel of Barnabas', which has Simon of Cyrene not merely carry the Cross, but get crucified in Jesus' place), they'll only get in a snit for the implicit denial of the Ascension--even they think Jesus is coming back.
What is with the secularists' facination with Magdelene? She gets a brief mention in the Gospels. Why don't these fools just go back to saying Jesus was gay, because there was one disciple "whom he loved?"
