If somebody is using Catholicism to support hateful views, we absolutely have a right to distinguish those views.  Similarly, when ISIS carries out attacks in the name of Islam, moderate Muslims unquestionably have a right, but not an obligation, to separate those actions from true Islam. That is not insecurity or immaturity, it is protecting a key part of one's identity. It's not meaningless to me when an Imam comes on TV to educate the public on what Islam actually teaches and call out ISIS for what it is. I certainly don't believe the Imam has a duty to distinguish his religion from these fanatics, but I appreciate it and don't see this as some meaningless expression of insecurity. I bet you don't either.
