I'm not attributing it to anyone in particular, I'm just trying to say, what does it matter if the person eats fish? If they walk into a shop and buy a non-meat product it will say "Suitable for Vegetarians", if they walk into a resaurant they will look at the "Vegetarian" menu, if they're at a friend's BBQ they will let them know they are "Vegetarian" so they don't get given meat.
If they want to eat fish then fine, their diet is Vegetarian + fish. Trying to create extra divisions is pointless, if a meal is suitable for Vegetarians then it is suitable for people who eat fish too. I don't see what all this fuss is about?
