A common advantageous strategy is to take the randomly-selected topic, however unrelated, and invent a chain of logic that claims that taking a given side/action leads to an infinitesimal risk of nuclear extinction/massive harms. This results in people arguing that e.g. "building more mass transit networks" is a bad idea because it leads to a tiny increase in the risk of extinction--via chains as silly as "mass transit expansion needs energy, increased energy production leads to more EM radiation, evil aliens--if they exist--are very marginally more likely to notice us due to increased radiation and wipe out the human race". That's not a made-up example.
The strategy is just like the LessWrongers' one: if you can put your opponent in the position of trying to reduce P(doom), you can argue that unless it's reduced to actual zero, the magnitude of the potential negative consequence is so severe as to overwhelm any consideration of its probability.
In competitive debate, this is a strong strategy. Not a cheat-code--there are plenty of ways around it--but common and enduring for many years.
As an aside: "debate", as practiced competitively, often bears little relation to "debate" as understood by the general public. There are two main families of competitive debate: one is more outward-facing and oriented towards rhetorical/communication/persuasion practice; the other is more ingrown and oriented towards persuading other debaters, in debate-community-specific terms, of which side should win. There's overlap, but the two tend to be practiced/judged by separate groups, according to different rubrics, and/or in different spaces or events. That second family is what I'm referring to above.
No one to my knowledge has ever argued that AI research should be prohibited because of a very small probability of its turning out extremely badly. This is entirely a straw man set up by people who want AI research to continue. Yudkowsky argues that if AI research is allowed to continue, then the natural expected outcome will be very bad (probably human extinction, but more exotic terrible outcomes are also possible) [1]. There are others who argue that no team or organization anywhere should engage in any program of development that has a 10% or more chance of ending the human race without there first being an extensive public debate followed by a vote in which everyone can participate, and this is their objection to any continuance of AI research.
[1] But don't take my word for it: here is Yudkowsky writing in Apr 2022 in https://www.lesswrong.com/posts/j9Q8bRmwCgXRYAgcJ/: "When Earth’s prospects are that far underwater in the basement of the logistic success curve, it may be hard to feel motivated about continuing to fight, since doubling our chances of survival will only take them from 0% to 0%. That's why I would suggest reframing the problem - especially on an emotional level - to helping humanity die with dignity, or rather, since even this goal is realistically unattainable at this point, die with slightly more dignity than would otherwise be counterfactually obtained."
