If you leave a game-playing, quasi-fantasy sports site because of the message boards, then you weren't here for the (revenue-generating) games anyway. Besides, the SPORTS debates around here are better than most other sites... it's the political and personal attacks that are irritating to many. And those are easily avoided, assuming you WANT to avoid them.
If you want to just play the games, there's plenty to keep you busy.
If you want to argue whether Edgar Martinez belongs in the HOF, well, there's that too. But nobody's forcing you to read a thread titled "Does Edgar belong in the HOF" or worse yet, "Trump-Worst President Ever". If you don't like arguments or people challenging or disputing your personal views, DON'T GO TO THOSE SITES. Play the games and enjoy your life.
