I don't have the links to your videos, no matter I'm not really that interested on why people choose to convert to Islam from Christianity or from Islam to Christianity or why they become atheists or anything else. Their reasons are their own and between themselves and there creator. It does not impact on my existence at all.

I believe that the only person who can be persuaded from the path God placed them on is weak in faith, if they leave that path by listening to "evidences" provided by people with agendas then that says a lot about them and what little importance they put on having faith. A Christian who is part of the living Gospel that is Christ will never forsake Him... You are welcome to the rest. :)

Peace.
