It is entirely pointless to argue with parasites. Their actions are not based on reason. They are driven by a relentless hunger for what you have. They will come up with any excuse, tell any lie, ignore any truth, to rationalize taking it from you. And when they can rationalize no more, they'll just keep taking it anyway. You don't talk them out of it. You make them stop. Or you watch them take it all. The only people worth trying to convince are those of your own flesh and blood, who have been fooled by your enemies' lies.
