It is opinion, it’s an unproven hypothesis, and an unproven hypothesis is an opinion, you can try dress it up with details about social networking all you like but it remains opinion because it’s untested for this game. Until you can show that everything in this game works better in groups of 15-25 it is. Also if and should don’t make something not opinion Eg I think everyone should support Scotland in football. Adding should hasn’t changed it from opinion
I’m not feeling anywhere near as argumentative as I was yesterday though so like with other things I just no longer care today. Believe what you like. Doesn’t matter.
