Why are so many young Muslims still so religous?

well... Muslims copy-paste Islamic dawah, Christians link to Apologetics

so, what ?

You are right but for me it is more.

We all know looking at the source is important because it can help in identifying bias. But in what world does "a Christian wrote that" qualify as refuting anything? If I were a Christian I wouldn't discount Algebra because of the involvement of Muslims in its development. I wouldn't justify beating my pets simply because Hitler was known for caring about animal welfare. Not to say these examples are equal but the article I linked wasn't simply an opinion piece; it was clearly well researched with references clearly stated.

There is a portal which shows the frequency of such changes in manuscripts: https://help.qurangateway.org/article/30-about-scribal-changes along with explanations which may account for some of them. I don't think it completely accounts for *everything* argued at https://carm.org/have-there-been-changes-in-the-quran and it definitely doesn't explain shifting interpretations due to changing dialects (or the various cultures in which Islam lives) but surely certain Islamic scholars have something to say and I respect that. The challenge has certainly helped Christianity and all religions justify themselves on the modern stage. As children and neophytes in our chosen beliefs or ideologies we typically adopt something because of how it appeals to our nature or because of the indoctrination of our family or societies but all that does is arm one for a fight. How can one hope to have a conversation, let alone convert another rational person to their cause?

At this point I could chase my tail forever... but to pull my head out of my @$$ because hussamhussam obviously does not care to discuss the infallibility of his beliefs... all I will say is that denigrating the source of information rather than addressing the argument is a worthless contribution to a conversation.
