The writer points out that which has been said many times. So called moderate muslims support and condone terrorism either in thought, word, deed, or by silence. Still, those that believe this to be true are chastised, called ill informed, even haters, often here by other FReepers for daring to say so.
IMO, the so-called "moderate" muslims are not "real" muslims. Any muslim who eschews jihad, and behaves in a generally civilized (i.e. western) manner is not adhering to the religion founded by Muhammed. It would be like comparing a committed Christian to Unitarians or secular humanists.
Islam was founded so that Muhammed could achieve prominence, and later, so that his followers could do so.
Other Christians would be screaming and condemning the action at lightening speed.
