Morally superior (in their minds) and hypersensitive vegans can be very entertaining!
On a homeschooling discussion site that was part of a larger vegan site one was not allowed to mention meat, dairy products, non-food animal products (e.g. leather), restaurants that served meat or dairy, or guns. Unless one was a vegan that made talking of normal life somewhat limiting. Not to mention not being able to post about field trips to restaurants, grocery stores, cheese-production plants, and livestock and dairy farms. There were occasions there when The Smug got rather thick, IYKWIM.
