Actually, it's a lot easier to find pet bunny only sites and pet bunny only forums than it is to find forums that are for meat rabbit folks or even allow the idea that rabbits are tasty. Try the House Rabbit Society folks, they're actually a touch whacked (IMHO) about what bunnies need, but they're very much not into meat buns.
On this site, there's lots of sub-forums which have nothing to do with meat buns, so perhaps being selective on this site may suit you? However, I find the meat bun folks to have a much wider knowledge base on health and breeding than the non-meat bun folks. The buns here are for fiber so we can make Hula Bunny yarn and things have vastly improved by using meat bun techniques for breeding, health and maintenance.
