I'm not impressed. You have a young man trading in one collection of superstitions for another. You can also find videos of Muslims switching to Christianity. You can find videos of Muslims and Christians turning away from their faith to become atheists. And videos of atheists going back to religion. None of it means anything. 99% of the population of the world could believe that the world was flat. That doesn't make the Earth flat, it just makes 99% of the people wrong. 99% of the people can believe in gods. That doesn't make gods real.
If you wish to convince me that Islam, or any religion, is true you must provide evidence! Real, testable evidence. Not testimonials, not anecdotes, not lists of believers. Show me how anything you believe can be true. If your god is all powerful as you claim, that should be simple for him.
