I think it's a great idea. In fact, maybe there should also be a separate forum for pescatarians as well. And how about a forum for vegetarians who don't check labels and so end up eating gelatine? Maybe a forum for vegans who eat honey and another one for vegans who don't wear wool? In fact scrub that, it's a bad idea.... too many forums. How about just two forums.... one for people who refrain from all animal products, don't support any company that exploits animals, don't drive cars in case of road-kill, wear face masks to avoid inhaling microbes, plant all their own veg by hand in order to avoid killing mice..... and one forum for everybody else.
Seriously.... we all exploit in one form or another. It's just a matter of degree. Vegetarian and vegan are just labels for stopping-off points on the ladder to perfection. Neither one should judge the other.
