I think this is both reflective of the nature of the Internet and a wider societal characteristic of America itself. Am I right to assume most of us are Americans? We Americans tend to treat the search for truth as a competitive thing.
Its not enough for us to search for the truth, we have to overcome our "opponent," we have to bludgeon him into submission, we have to "win." We need to become better listeners. We need to learn how to approach discourse in a more open spirit, with a willingness to hear our conversation partner and even be changed. We should be grasping for understanding together, not in spite of the other, not before the other, etc.
We're a very talkative society. We don't do very well when it comes to listening. This combative approach to discourse infects everything, politics, it goes without saying, religion, everything. One commentor said give people anonymity of the Internet and they turn into complete jerks.
I'll just close with this. I enjoy HubPages very much and I like the community; work hard on your hubs, you'll attract positive, helpful comments in the main; but if your looking for more, like a discussion of ideas, and heaven help us, even debate; if you, in any way, are looking for constructive, civil discourse about a wide variety of ideas, a "give and take," you best stay out of the forums -- they turn bad and mean very, very quickly, as you know.
