Generally my rule is not to ascribe to malice anything that which can be explained by stupidity.

Anyone is capable of anything. We don't know which among us is capable but it doesn't matter, his argument tries to argue against that general principle, then describe a scenario that someone made up in their head without any specific evidence and expect you to explain why it didn't happen.

Sounds like any religious story from hundreds of years ago that someone expects you to disprove. It's simply stupid. But at least not malice.

Don't bother.
