There is a clear and definitive paradox in human existence:
While our intellectual brain loathes killing, our animal brain aches to kill, and we must kill to live.
So, in the many conversations that could emerge from such a subject, I choose viruses. Initially, the real ones- we try to get rid of them if they effect us badly. People spend their lives researching how to be rid of them. Millions of dollars are spent trying to get rid of them. the viruses themselves aren't ACTIVELY fighting this, they just exist, and pervasively so.
Now we click over to other viruses. The kind people make on purpose. I'll include in this malware, spyware, crapware, e-mail spam, junk mail, flyers under your car's windshield wiper, etc.
We do not have people devoting their lives and industries spending fortunes to ensure the eradication of these viruses. Certainly, there are companies combatting spam, viruses, etc. But as we all know: in war you go after the factories where the tanks are made, and not nearly as much, the tanks themselves.
There is no industry devoted to killing off the makers of these viruses.
The message should be clear: hey you schmucks, we'd really kind of like to see you strung up. knock it off, hey? you know, before you make me pull this car over, and then you'll really regret it.
And it's our dumb humanity getting in the way again. These viruses are legitimized by their makers being human. And thus we are forced to put up with them.
...and to put to rest the plural of virus: "The word virus never had a plural form in Latin. In antiquity the word had not yet acquired its current meaning. It denoted something like toxicity; venom; a poisonous, deleterious, or unpleasant agent or principle; or poison in the abstract or general sense." - taken from wikipedia
