I didn't vote because I consider the benefits of a forum to be about growth and insight, not changing each others' beliefs.
We provide each other reminders, conviction, comparisons, new ideas... but why would it be important to change someone's theology? I am not out to recruit and pull members from one team to another.
This particular Advice section is often used for bringing understanding to a situation. Getting input on how people perceive situations, and then finding ways to solve predicaments. True, there are people who are stubborn and might be heading into extreme beliefs... with no intent on changing. But change for the sake of change or open-mindedness... that seems impractical and just as manipulative as stubborn viewpoints.
I suspect there are certain issues you are referring to, that seem to continually hit brick walls. Remember that the people who post are often posting because a reaction stirred within them. Five or ten respondents do not represent the whole of Christianity, or of members here -- it is the people who see a challenge they want to address.
Posting is often about taking on a challenge (like it or not). If there is no controversy at all, the post will be too boring or obvious to respond to. Imagine a post that says, "Jesus is Lord." People shrug and move on. "Jesus is Lord of all," a few people would bring up whether He is ruler over people who don't believe in Him. Narrow down to "Jesus is Lord of Las Vegas," and you have a deluge of rigid input, defending all sides.
Is that a bad thing, to voice an opinion firmly? Those firm opinions are the same things that bring variety to a forum. If everyone were too open-minded, there would be nothing to discuss, nothing to learn from. We need a little rigidity, to get a good discussion going. Iron sharpening iron.
