Spouting a redundancy is no substitute for learning.  Guess it pretty well establishes your position vis-a-vis learning vs. ignorance, though.

Let's see if a recap will help you get it, shall we?

(1) I said Da'esh are not Islamic.  Why?  Because they're egregious violators of its authentic tenets (including al-Shari'a).
(2) You asked "According to who?"
(3) I replied, according to every existing Muslim "sect" (school of jurispridunce) in existance.  Salafis like the Da'esh ("Isis") aren't a recognized Muslim sect.
(4) You said that pointing out that no existing Muslim sect recognizes this group as MUSLIM is the same as saying "All Nazis aren't bad."
(5) I pointed out it's the same as saying all German Lutherans aren't Nazis.
(6) You replied with an obviously meaningless redundancy.

Hopefully if you review arguments (1) through (5) you'll figure out that your final argument is irrelevant and incoherent.  That means it doesn't apply to the discussion and makes no sense.

Thank you.
