The YouTube ban is more based on emotion and "hey, we support the Islam too!" rather than Islamic law or being Muslim. There have been plenty of videos attacking Islam on YouTube for years now, so why is ALL of YouTube only banned because of this one?
As a practicing Muslim /.er, it saddens me to see the people who are supposed to be the most open-minded and questioning often believe the media blindly when it comes to Islam. The media makes a big deal out of certain events, doesn't even mention others, and uses words cleverly to change the mentality of the people. For example, about the same time as the Malala incident, an Afghan girl recently died of internal bleeding due to being raped repeatedly by US troops. Unfortunately she wasn't named Malala...
The media will essentially give the impression that "look - look at what these bad Muslims are doing!" without considering economic and political factors as well. Often "Muslims" or "Islamic extremists" are blamed for incidents completely political in nature (often committed by Muslims or secularists living in Muslim countries). Also, they will take the actions of an extreme minority and use such words, take such pictures that it will make you think they are the majority. Hence "those crazy Muslims". Take the recent attacks on the US embassy for example. I've BEEN to protests in the USA where atheist groups have thrown molotov cocktails. There have been plenty of incidents in which anarchists will cause illegal violence, such as getting on top of police cars and smashing them, during protests. But we don't think that all protesters are like that, do we? We don't hear about those incidents, do we? There's a reason for that.
All I will say is, let those who seek the truth, seek the truth, and let those who blindly follow, blindly follow.
