When statements are attributed to those who made them, or groups are identified by the leaders they follow, this is merely for identification and clarification. Praise and blame, allegiance and hostility, however, are to be based on the designations mentioned in the noble Quran, such as Muslim and disbeliever, believer and hypocrite, righteous and wicked, truthful and lying, those who put things right and those who spread corruption, and the like.
