Self-reflection does not mean introspection.  Christians, Jews,  Hindus, Buddhists, and other religions  ask followers to look inwards to meditate on their own character and soul.  This has nothing to do with self analysis. That may lead to  questions about Islamic Suprematism and that is apostasy, which is punishable with death.   This is only a call to arms against those who criticize Islam for what ever reason.
