Years ago, political speech was allowed in the former site we used. It got ugly, rather quickly. People who had been cordial on line with fans of other schools, and their school, suddenly became enemies on all points. They would snipe at each other about their own team. Anything said was countered, whereas before they might have offered an alternative explanation for whatever, now suddenly there would be this vituperative argument.
So, it was banned. And the board cleaned up, people went back to discussing sports rather amicably with the usual sports barbs thrown out mostly in good humor.
If you want a cess pool where you can say nearly everything, there is a site for that in spades. If you want to focus on sports and cooking and beer and amicable discussion, this place is reserved for that.
