I came to this realization after getting good at climate science arguments. I could take a denialist "did you consider" argument, go to the IPCC reports, find labs, find papers, and return with summaries and citations in relatively short order, and after delivering them with kid gloves I could move people off one denialist argument... and onto another. If I repeated the exercise, there would be a third in line.
Bad arguments take 1 unit of effort to generate and 1000 to refute. If you don't have a strategy for handling that asymmetry, you're toast, and the strategies for handling it do not involve kid gloves. Gish gallopers are gonna Gish gallop, and no amount of good faith is going to stop them if they don't want to stop. At some point you have to give up on the unbounded cost of good faith and call out the bad faith arguments. If you put them on blast, you might persuade spectators and that's about the best you can hope for on a finite budget.
