I'm old enough to have "shifted" substantially on various issues over time. Much of the perception of my beliefs in the Bloggernacle is based on the fact that I don't like inconsistency and one-sided arguments - so I end up addressing comments that exhibit those traits. Those comments tend to be the most extreme on both sides. That means I end up on predominantly liberal sites being called too conservative, while I end up on predominantly conservative sites being called too liberal - all because I tend to believe the best solutions lie somewhere in the middle of the extremes in most cases.
Frankly, and as bluntly as I can say this while still grinning from ear to ear, I have found that my current path is MUCH harder to walk and requires a complete lack of complacency - while advocating most extremes is incredibly easy. It's very difficult and taxing to read every single comment in a post before commenting, try to read very carefully every word everyone says, remember the gist and general content of every comment, go back and re-read former comments prior to responding to make sure I don't misinterpret, consider each word in a comment to which I respond and what it might mean, look for any ways to read others' comments charitably (seeing, for example, where a particular word used probably, based on overall context, means what a different word would have conveyed better), contemplate the best way to structure a response, re-read each response I construct, edit it at least once before submitting it, etc. Honestly, I go through that process almost every time I comment (and regret it almost every time I don't), and there is no complacency involved in it.
I try to tackle every issue of every topic that same way - reading each and every comment for insight into how it can influence my own view of the topic. This approach has molded my view on many issues over the years, and those views have changed and continue to change. It's just that I tend to respond in public settings to the comments that are the most extreme (on both sides of whatever the issue is being discussed), so my comments on group blogs generally are more in response to others than passionate statements of my own beliefs. As I have spent more time in the Bloggernacle, I have written those (passionate statements of my own beliefs) in group settings more often, but they are nowhere near the majority of my comments.
