In contrast with that, people from the "networking" world often look with despise to people who don't understand what they do and want to prevent them from learning, they love to just say what is wrong and never point to what would be right and why, they also will most of the times just keep saying they must hire someone to do the job instead of learning.
That is my experience on Networking Stack Exchange, on ##networking channel on Freenode and also the impression I have from a friend that deals with networking, although I try to not talk about it with him for the reasons above.
However, I have also contributed to Stack Overflow and managed IRC channels and servers. The negative traits you've described do correlate to the hostile attitudes endemic within many StackExchange and IRC communities. They are not correlated to my workplace experience of network engineers.
On the whole, network engineers are a cool bunch though. They’re often called in to make stuff work without any real background or understanding of wtf is going on in advance. As a profession, they don’t get the respect they are do.
Or if they show up, it's counterbalanced by a giant number of nice programmers willing to help. While on the Networking StackExchange they are the only ones.
You haven't met enough programmers, then. :)
