coffin_dodger, can you address the patent impossibility (if not live up to the revealing psychodynamics) of your preposterous claim that you've researched every single one of your presumably tens of thousands of ancestors dating back to 1650, and assured yourself that none of them whatsoever had any proclivities to commit evil or violence?
Or was that supposed to be satire of some kind?

Here is a mathematical certainty about some of the people we ALL have in our genetic ancestry, without exception: royalty (self-deigned, as in all such cases), rapists, murderers, child abusers, sadists, mass killers and mass rapists, and, of course, wily and cunning conspirators to crimes of genocide, mass killing and mass rape. I think something like 60% of the world's population has just Genghis Khan in there. You need not go back very many centuries to guarantee that we all have such characters in there.
We can all stand to GTFOO.
