The point is this: like the allah of mohammed-worship, the God of Abraham (who is embraced whole-heartedly by the sociopath mohammed in his absurd construction of a religion whose point is the worship of mohammed) is an Entity pleased by the arbitrary and pointless suffering of men.
Abraham necessarily says to himself, if God wants me to do it, I must do it. It is not the same thing as saying, for instance, if God wants me to be kind to others, I ought to be kind to others. It has only to do with the whim of the Supreme Being.
The concept of the whim of a Supreme Being is the gist of mohammed-worship. (The trick to islam, is that mohammed was the conscious stand-in for allah).
There is no difference in the logical premise of mohammed-worship and Christianity or Judaism, for example. Our President knows this, if only subliminally. He is not capable of confronting our enemy, because he shares the same interior premise: God is worthy of obedience even if he dictates the totally inane and brutal sacrifice of a son, especially under circumstances where the sacrifice is a sadistic emotional/psychological event.
The worship of mohammed is a particularly debasing and humiliating, and emotionally cruel circumstance. There is nothing satisfactory from a human pov, other than the debatble satisfaction of belief in monotheism.
But the belief in monotheism, and all it implies, calls into question islam and other "Abrahamic" religions.
Our President is not a deep thinker. I do not say that in disrespect. I abhor his critics, who are witless jackasses, mostly. His belief system, tho, prevents him from uderstanding the enemy. He realizes (at some level of understanding) that the best criticism of our enemy, implicates his own beliefs.
Islam is not an "Abrahamic" religion, whatever that is.
Abraham is the biological progenitor of the Arabs, through his son Ishmael. Arab is not an equivalent of Muslim. The fact of Abraham's monotheism is claimed by some to link his religious beliefs system to Islam because Islam is monotheistic. But the God of Abraham is not the god of Islam. And, of course, Muslims reject the doctrine that Abraham's One God is manifested in three persons, the Trinity.
