Once an evil man wrote his fantasies on the Internet about a woman being attacked and beaten.
This man had a very high opinion of himself, so he didn't understand that writing violent fantasies about actual people with real names on the Internet is deeply offensive and even threatening.
And dozens of people who also enjoy reading about women being beaten clapped.
I would add that your creepy little parable comes down to exactly this, no more and no less: "The enemy of my enemy is my friend." Only the most paranoid and crazy person would believe that and it's impossible to make a coherent intellectual argument for this case and you don't even try.
But by instead spewing your violent attack fantasies out, you make any sort of rational discussion impossible.
So creepy.
