I respectively disagree. I do know some people that have researched on Islam but have come to the conclusion that it isn't god's religion. There are also those who leave Islam after so many years as Muslims. Of course, we don't know if they were strong Muslims but it just shows that Muslims can't all be grounded to their faith.
