Meh, it is supposed to be a provocation, but is a completely harmless one. It's not like they are doing bodily harm to anyone or destroying anyone elses property. Of course there are nutjobs out there that does it due to racisim, but that it so transparent and obvious that anyone should be able to write it of as such. But I also think that it can be a legit demonstration agains a system that has wronged them or against something horrific that has been done in the name of and/or by partisipants of whatever religion.
