Read the article. It was NOT a rant but the standard jihadi warning of an attack.
What they are not telling you (or perhaps they are still so ignorant about) is that this is no “rant” and “making peace with “dawla in al sham” is (unlike what they stated) is a “threat of violence”. ... They do not comprehend the basics of Islam and its method of communication. Artan was giving out the standard Islamic “Aslim Taslam,” the mandate by Islam “make peace (by submission) and be at peace” or face the consequences. Islam mandates that such a declaration be sent out to justify an attack.
I suspect it is both a rant and a warning, my good FRiend.
BTW, one online dic defines "rant"..."Violent or extravagant speech or writing."
