There was a terrorist attack in Israel the other day. You didn’t likely hear about it for two reasons: first off, because it was in Israel, and we kind of regard these things as “normal” there, unless it’s a really large attack. Second, the terrorist wasn’t a Muslim; he was a Jew.
Now to be quite honest, I won’t say that this was terrorism, though I can’t figure out why not. You have a man motivated by religious belief to stab six innocent people because of their homosexuality (real or perceived). If this happened in the USA against, say, a group of Christians and was done by a Muslim, well, do you think the media would call it anything other than terrorism?
This gets to something I said two years ago. “Terrorism” is basically a useless word that can mean whatever the media and government decides it means at any given point. It is, therefore, in society’s best interest to stop using it as soon as possible and simply stick with other words, like “criminal”.
