So I watched the video and now I'm wondering what exactly that has to do with being a Muslim. It's actually pretty obvious. In your mind you think believing in a religion ultimately has anything more to do than the simple bottom line. Is this religion true or not? Everything else is a distraction. I'm glad this wadaad doesn't think criticism of Islam is islamaphobia that's nice, but what matters when it comes to believing in Islam is this. Do you genuinely believe that Muhammad was spoken to by an angel in that cave?
If so, why? If a man were to come to you today presenting the very same claim with the same lack of evidence would you believe this man? Of course you wouldn't, because you're a rational human being. You aren't a Muslim because you were presented this story, put some hard thought into it and then accepted it as truth. You were raised into it.
Ask yourself this. Is it just a coincidence that you happened to be born into the one true religion? Or is there potentially another explanation. That perhaps you just like every other person who ever lived also thought of themselves as being born into the true faith no matter how different those faiths were. Ask yourself that if Allah really did communicate with mankind why would he use a similar method as with all the other false religions? That he would enlighten one man with direct evidence and expect everyone else across the world for the rest of time to believe purely out of hearsay.
Use a bit of intellectual honesty and ask yourself why you are a Muslim. What compelling piece of information did you find? That when you found that piece of information if you used the same standard of skepticism you would use for any other claim you come across. That you aren't making a conclusion that it's true first, and working backwards to look for supporting evidence.
None of the so called evidence for Islam is close to compelling. It's as far-reaching and shallow as the evidence for any other religion. What's especially funny is how Christians and Muslims will look at the same piece of evidence and come to dramatically different conclusions. It's also not a coincidence that the conclusions they find just so happen to confirm their previously held beliefs.
