Sorry, I think this is borderline propaganda.
It's most unfortunate, that is all HuffPo has become these days. Anti-Christian, anti-white, anti-western propaganda. Where is the objective reporting? Where is the balance? Is everything now 100% op-ed? Seems so.
As much as I personally think fundamentalist Christians are a bunch of lunatics, they can't be seriously compared to ISIS or the dozens of other radical Islamic terror groups out there that all formed around Islam. From Boko Haram to Jaish e Mohammed, the main goal is conquest by force or death through Islam.
When an Islamic terror attack occurs, the first response I hear from outlets like HufffPo is, "but the Crusades!" Pathetic and very, very telling. Which is why the situation is spiraling out of control.
