I feel it's important to draw a distinction between an ISIS member and and ISIS sympathiser. So far, is sounds like this man was the latter. A "Lone Wolf" hateful individual who planned and carried out his attack on his own, driven mostly by his own personal hatred of homosexuality - a hatred that probably THEN lead him to identify with ISIS ideology. As opposed to an ISIS "member" who planned an atrocity as part of a cell under the instruction of ISIS superiors.

ISIS will take credit for anything and that's why it's important to be accurate in reporting what has actually happened... There's a REASON they want to take credit, and they should not be allowed to every time a lone psychopath decides to mention IS, Islam or Allah during their attack. It gives people the false impression that they are organising these events, which makes them more terrifying, and so achieves their goal: to spread terror.
