To all the copywriters, the reporters, the news announcers and assorted talking heads; please stop referring to terrorists as “lone wolves”. You are inferring a dignity and natural beauty that they do not possess. If you, absolutely, must use some sort of simile, then may I suggest a slug? These lone terrorist operators have far more in common with a slug than the wolf.
Like the slug, these lone operators wallow in the muck and the dirt, they feed off what has been created by others. They attempt to destroy what is beautiful, one bite at a time. They seek to take sustenance from what is not theirs to take and have had no hand in building.
Lone slugs is so much more apropos.
