Ah. Islam or die. Or pay jizya and zakat.
The Legacy of Jihad: Islamic Holy War and the Fate of Non-Muslims (Andrew Bostom)
and
The Suicide of Reason: Radical Islam's Threat to the West (Lee Harris)
Islam is a serial murderer of entire cultures and peoples. This is what is has done throughout it s entire history. Those whom it does not destroy, it enslaves and impoverishes. Islam lays waste every land that it inhabits.
We need to clean our own house first. Then we need to send a clear and simple message to Islam: "Threaten our civilization and yours is forfeit." Then back it up in the only terms they'll understand.
