The issue is using civil infrastructure as weapon, that could arguably be an act of terror. As pagers are rarely used in non-criminal settings, i guess this is somewhat okay in my opinion, but the callousness and overall reactions (proudness, smugness) of israelis and most of the west on this near-terror attack is in my opinion another proof of a lack of empathy that is starting to be pervasive in our societies.
I know people talk about the "entitlement epidemic", but entitlement is just another name from narcissism, in essence a lack of empathy. Which seems to be more and more socially acceptable and even rewarded (with internet points mostly), like your comment show (i'm not jumping on you, you are tamer than many, so i think it's a better exemple for my point than more violent ones).
And since that's the example we show our kids today, i'm now officially more worried about our society ability to handle social media than climate change.
