I think you’re positing two different ideas - one is boredom the other is disenchantment.
If I was bored - it would mean that my faith or devotion was weak and transient if external forces caused me to lose interest in my religion.
On the other hand, being disenchanted because of how certain people (the hardliner mullah types) promote a perverted view of Islam is understandable, but speaking for myself, it makes me ask questions and seek my own answers instead of relying on others for their interpretation of Islam. This in turn brings me closer to Islam because I have a reasoned understanding of my faith instead of blind following.
