I learned long ago that trying to get in on a conversation about things I don't care about, know little to nothing about and don't want to learn was a waste of my time and the time of the other people involved. Maybe it means I have fewer conversations. It's like if were a baseball fan but didn't like (American) football yet I still went to NFL sites on baseball's off season only to compare the game to baseball and how I like baseball but will never care for football. Then go on to say football would be so much better if it had 9 innings. It just doesn't really apply.
On a related note, I don't see the comparison of 70s football to today's football analogy as being particularly close when talking about specific rules and decisions. The D&D game has evolved pretty dramatically since the 70s, it would be like if the NFL decided that they should play touch football and use frisbees.

I do occasionally discuss how we approached the game back in ye' olden days, but that's just relating how we used the rules to play the game we wanted.
But some of the comments are also more general, and you were the one who put yourself into a specific group of posters. So if some of the comments describe square pegs when you identify as more of a rectangular peg ... and now I realize I'm all out of analogies and haven't had enough caffeine this morning.
