Anecdotal reports by terrorists is the best data we have available. Weak evidence is still evidence. We should update on whatever evidence we have, and avoid dismissing it out of hand and calling it ridiculous. As aspiring rationalists, we need to orient toward the truth, and avoid confirmation bias.

Which explains why you ignored all the reports that didn't fit your conclusion, e.g., the ones about how ISIS is planning to conquer Europe and considers this a war. You don't win a war by worrying about not offending the other side.
Here's my op-ed that uses long-term orientation, probabilistic thinking, numeracy, consider the alternative, reaching our actual goals, avoiding intuitive emotional reactions and attention bias, and other rationality techniques to suggest more rational responses to the Paris attacks and the ISIS threat. It's published in the Sunday edition of The Plain Dealer, a major newspaper (16th in the US). This is part of my broader project, Intentional Insights, of conveying rational thinking, including about politics, to a broad audience to raise the sanity waterline.
