How the **** one "converts" to a belief system is beyond me.
To believe X = to be convinced that X is true - this is an involuntary action. You can't just start "believing" something because you want to - you have to be CONVINCED that something is true. Now people can be convinced for good reasons, or bad reasons, but nonetheless, they have to be convinced its true in order to believe it.
islam makes some pretty bold truth claims - in order to be a muslim, one must accept those claims to be true. Now, there are two options here:
1. You are convinced that those claims are true
2. You are not convinced that those claims are true
That's it. If you are convinced, you are a muslim. If you are not convinced - you are not a muslim. This is where I am puzzled - how does saying "blabity blabity blah" makes you a muslim if you are not convinced to begin with?
