Islam is a set of ideas. It is an ideology. It inherently deserves no more or less respect than any other ideology. That is to say, it inherently deserves no respect whatsoever. Just like any other idea or ideology, Islam also deserves no special protection from criticism or critique. Affording it any such privilege just because it has a supernatural origin story is not compatible with reason. Muslims, on the other hand, are people who have adopted Islam as dogma. It should really go without saying that just like any other person, Muslims inherently deserve to be respected as people, treated with dignity, and have their rights protected.
All religions, new and old, should be subject to the same disrespect that Charlie Hedbo so boldly and bravely paid them. As Salman Rushdie, a man who knows a thing or two about this subject, said religion deserves our 'fearless disrespect'. Long may such disrespect, whether it be in Charlie Hedbo or elsewhere, continue.
Charlie Hebdo absolutely got it right when they stood and criticised Islam. While others may have shirked away from criticising Islam Charlie Hebdo was on the forefront of defending free speech. It doesn't matter how sacred Muslims may revere the Prophet Muhammad because everyone is allowed to have an opinion.
