Trying to rationalise terrorist attacks and minimise their links to a terrorist organisations is pointless as we are battling ideas not organisations.The organisations came from the ideology, the ideology did not come from the organisations.
The media and effete powers-that-be have been twisting themselves into Halal pretzels Islamsplainin’, rationalizing how a given Muslim terrorist attack isn’t really “Islamic” or isn’t significant. These contortions can become quite ridiculous, such as suggesting that recent Allahu Akbar-shouting Munich shooter Ali Sonboly might somehow have had “right-wing” motives because, among his violent passions, was an interest in Norwegian mass murderer Anders Breivik.
A more common (un)intellectual contortion is the minimizing tactic of claiming, as is politically correct authorities’ wont, that a given jihadist attacker “has no ties to IS” (the Islamic State), as if there’s nothing to see here if a man doesn’t provide notarized evidence of allegiance to the boogeyman du jour. Yet this is much as if we’d claimed during the Cold War that a Marxist terrorist attack wasn’t really a Marxist™ terrorist attack because we couldn’t find a connection to the Soviet Union. The issue and problem wasn’t primarily the Soviet Union but communism (Marxism birthed the USSR, not the other way around), an evil ideology that wreaks havoc wherever it takes hold. Likewise, the IS didn’t birth Islam; Islam birthed the IS.
