Any message board that does not involve animal rights would be considered an omni message board. For me, a music message board named Pulse Music Board is the worst I've ever been on. Sports boards have been very bad as well. Vegetarian boards have been much better than omni boards. A lot of immaturity and it makes me think worse of humanity.I don't think I've ever come across a site dedicated to meat eating unless it was a tie-in to a restaurant or a fad diet.
Since about 95% of the people on Earth are Omnis, then it would follow,that most message boards are onmi message boards - whether or not they specifically identify themselves as such.
But if you don't go out of your way to identify yourself as a veg*n on those boards, no one would know....
I attended a couple of tailgate parties with some of them, and my vegan chocolate chip cookies were the talk of the board.
Anne Chovie can make a similar claim to fame, Ledders.
She once had to turn down an invite to an omni freind's party.
She was forgiven in return for supplying the party hostess with a large pot of her chili non-carne anyway.
