What is the cause of those crimes? You are switching from incidents of violence arising entirely from some specific incident, to those cause by sentiment, e.g. 9/11 caused an increase in anti-Muslim violence.
It relates because you said this distinguishes Charlie Hebdo from killing Muslims burning a flag. If they all have negative sentiment, and they all commit hate crime unprovoked, or provoked by disrespect to culture and icons, then the problem is not unique to one of them.
There are non-Muslim states that will execute people for disrespectful depictions, so I can't see how this is a uniquely Muslim problem.
