Ideological flamewar isn't allowed here regardless of how wrong someone else is. Same for personal attacks. We ban accounts that do these things.

Fortunately, from your recent history it looks like you don't have a habit of doing this on HN, but would you please read https://news.ycombinator.com/newsguidelines.html and take the spirit of this site to heart? The idea is something like this: If you have a substantive point to make, make it thoughtfully; if you don't, please don't comment until you do.

That was a detailed comment that didn't say "government is bad." It laid out a pretty reasonable interpretation of why that decision might have taken place, including quite clearly pointing out that some governments care less about the effects of airports on local populations, which could explain why some markets still have hub airports.

It definitely tallies with the impression I have – looking at London Heathrow, for example, where the controversy about expanding the airport has been rumbling on for an age, and governments are consistently jittery about taking an obvious view on it. I'd say there are pretty good reasons for avoiding expansion, but obviously this other comment disagrees.

There's nothing here that screams "libertarian," just a possibly inaccurate, but hardly unreasonable, point of view.

To be fair, there are lots of ideologies which provide "for all problems P, X is the answer". Capitalism, Marxism, many flavors of religion.

Fanatic behavior adds that "no problem Q can be as important as problem P (for which we know the answer is X), so we don't need to discuss it except to figure out how Q is related to P".

You get that with any ideology really. If you can reduce all the scope of all the problems in the world into a single variable, you can now blame everything on that single variable. Everything seems so easy and simple while in fact you are just being lazy.
