Sweetie-you wrote this ""pale in comparison to the damage done by right wing terrorists here, like right wing hero Timothy McVeigh of OKC bombing infamy, or the Birmingham church..." 
And I am telling you to condemn one, you must condemn all (and so that includes ALL Muslims for the radical murderous behavior of other Muslims in terrorists attacks just as you condemn all right wing thinking conservatives for the behavior of three murderous ones.) 

Or do not condemn at all.

Your choice. Cannot have it both ways.
