A gish gallop is an asymmetric attack. They can produce nonsense faster than, say, a physicist can produce physics or a mathematician proofs; and usually have nothing else to do with their time. But in a policy debate framework both sides have equal time, neither is doing original research and both are expected to cite qualified evidence, the judge understands the structural flow of the arguments, and you can say "this is nonsense" faster than they can "explain" the point. Or as Wikipedia even says: Generally, it is more difficult to use the Gish gallop in a structured debate than a free-form one.
