Bear in mind that on the internet (GZ included) there's usually a woefully low standard of discourse involved in any issue that involves political subject matter.
I don't agree with that. In my experience, the discourse on GZ is usually way ahead of the imbecilic name-calling and trading of insults that tends to pass for discourse on many other forums (cough, Stuff comments, cough). With some exceptions, most people seem to be pretty good about debating ideas and concepts without resorting to insults and crude jibes.
Of course, like all discussions where involving issues that people feel strongly about, things will sometimes get out of hand. But MF does a good job at quickly jumping on boorish behaviour, which keeps things fairly civil almost all the time.
