Call it for what it is. Some posters here would have no problem calling out White Terrorism, so call out Islamic terrorism. Stop beating around the bush.
Except this is not Islamic terrorism. We don't know even know who is responsible yet. Given past events, it may be ISIS related, which would be part of an extremist faction completely unrepresentative of Islam.
Would you call, let's say, the LRA representative of Christianity? We can argue about the scale, but I can't possibly subscribe to this line of thinking.
ISIS are obviously not "representative" of Islam but that doesn't mean they don't base their actions on Islamic scripture and theology. Baruch Goldstein surely wasn't "representative" of Judaism and yet that doesn't mean it wasn't Jewish terrorism either. But that was one attack, and it now seems we can't even have a week without Islamic terrorism in Europe. Doesn't mean most Muslims agree with it, that's fortunately not the case, but let's not lie to ourselves about the source of these radicals' thoughts.
Edit: Crabcake formulated this way more eloquently. I agree with him.
