@menelion A strange conclusion to leap to. There are plenty of non-Islamic people who are just as filled with hatred for anyone not "like them". The AfD, for example, who with no apparent trace of self-awareness reacted to the event by denouncing violence and intolerance(!).
Maybe ask yourself why you "were sure about the fact" before you had any evidence at all.
