It takes time to have a serious debate. You both need to figure out what your unstated premises are. If you disagree on these, you won't get anywhere by arguing downstream of them. Politics is even worse, because you are supposed to have an opinion, but at the same time, most matters require a detailed understanding of the facts that few people have the time, brains or inclination to understand. Add the tribalism and this gets even worse. It's incredibly rare to find someone whose general political opinions are well thought-through. Mine certainly aren't. I could regurgitate the argument for the free market or for heavy gov control of the economy, for example, and even understand them as internally-consistent syllogisms, but really all I'm doing is linking concepts together in my mind; I doubt any of them apply to any really-existing concrete situation that any given country is in. Hence I try not to comment on political threads.
