How about this: the GP was clearly communicating a all-but-obvious conclusion based on the the demonstrated, highly publicized, and widely available evidence to anyone who has paid a modicum of attention. For Trump and his team: the motives are the substance!

At this point I do not think it is reasonable for an informed participant in this conversation to demand every attack on the motives of the current administration given the overt words, policy and behavioral choices supporting such a conclusion. The GP wasn't speculating or prepping for debate club, they were summarizing a (seemingly) obvious conclusion. That you agree with me tells me you know at least some of this.

This isn't a debate class where we score points on technical merit. Do you disagree with the point being made, or were you just having fun demanding the GP show their homework? But perhaps in fairness, I've moved the goalposts. Yet once again I would say: it seems a distraction from the obvious larger, more important, easily demonstrated point.
