Well, to turn Harris' own idea against himself, his "moderate" atheist views also encourages vicious people to justify atrocities in middle east in the name of "fighting Islamic terrorism".
What he is demanding is there should fear-free, public discussions about various evils of Islam: e.g. pedophilia practiced by Islam's prophet Muhammad, Allah's misogyny and Allah's very existence and so on.
How does this justify your claim?
