Meh.
I form my opinions by reading, playing, and assessing the rules. I find the discussion useful to test and evaluate my opinions, because I may not have considered all of the factors involved, and other people may have. That occasionally changes my opinions.
For this sort of thing I do find discussion on the internet is more useful than face-to-face discussion. In face-to-face discussion, personality often overwhelms argument, and the loudest or most belligerent may cow others. On the internet, the loudest and most belligerent is just a wall of text to skip over to get to the next well-reasoned argument.
