Let us not dignify the mad psycho-killers who went on a rampage in Paris last night with the title of "terrorists"; there is very little dignity to the title of "terrorist" – they are after all scum of the earth, but these mad psycho-killers are too contemptible for even that status.
If as is likely that the mad psycho-killers were aligned with ISIS, let us not call them muslims; let us instead call them islamic apostates. There is nothing that will insult them and those who would follow in their footsteps more than to call them apostates.
And to those who would blame Syrian refugees (like the fascist I unfriended last night) :-
