First, the reference to level of membership in the box to the left refers to the number of posts. I believe that one is a Junior member until s/he reaches 100 posts. Then the title changes automatically to Senior.
The people who come on here seem to already have well thought out views. The majority are secular, but some at theists. There doesn’t seem to be any correlation between the person’s age and his/her ego level or intelligence. We have quite a few bright, thoughtful members of all ages but we’ve also had some loudmouthed jerks from quite young to elderly.
I don’t see this forum as a place to change people’s views. Rather, it serves the purpose of us exchanging ideas and, I hope, sharpening or clarifying our own present thinking.
