The correct response to a Gish Gallop isn’t a Gish Gallop of your own, it’s to keep to one subject at a time. Don’t let them throw a thousand claims at you; if they do, only acknowledge one and work through it until the conversation is finished, no matter how many times or how provocatively they try to lead you to a dozen dead-end points that they have no intention of defending in good faith.
