Which AFL team has the most pasionate support which one should I support and why?

Most pionate, i would say Richmond, Carlton, Collingwood, Geelong. Most Vic clubs have a pionate & loyal support base. Some bigger interstate clubs have a lot of bandwagon support. I support Richmond, but they have caused me a lot of stress over the years......you should get on the Cats, they could dominate for a while to come.
