This thread doesn't fit that pattern largely because LW users are aware of the problems with talking about politics and are more likely to stay on the meta-level as a response to that. There is, in fact, not a single argument for/against brexit in this thread, which I think is a shining advertisement for LW comment culture. On the other hand, I think this article is also particularly well-suited for not immediately inspiring object-level argument, at least as long as it's not posted on /r/news or similar.
