Calling someone a consistently bad analyst is a personal statement. I agree with justme, that we show someone’s analysis is bad by showing the weakness in their arguments and then everyone can see it was a bad analysis.
Professionals debate the topic, not the person. Hugo Chavez’s inability to stick to that dictum made him look like a “comic strip cartoon”. Instead of laying out why he disagrees with our policies, he started name calling. That made him look like a kid with a tantrum, and it was hard for anybody at the U.N. to take him seriously after that. (Any other comments about Chavez, please start a new thread; let’s save this one for “staying on topic”).
