they're desperate for a title.
i know that a lot of people are in a situation where it's difficult to give up all meat (for example: kids who say their parents make them eat fish) but they shouldn't call themselves any type of vegetarian when they're not one. why not just tell people that you're a "vegetarian in training" or that you're working towards going veg but haven't given up chicken yet......i don't see why they want to label it so badly. when someone offers you a steak just say, "no thanks...i only eat chicken." what's so bad about that?
i don't like words like flexitarian, semi-vegetarian, pollo-vegetarian, etc. because they mean NOTHING.....it's just a fancy word for, "i still eat meat, but only certain kinds or only when i really want it." it's completely ridiculous.
they only term that is valid in my eyes is "pescetarian" so long as they don't claim that it's a type of vegetarian. IMO, pescetarian is valid because a lot of people have religious beliefs that lead them to look at fish differently than they look at other meats. catholics, for example, don't view fish as meat. in instances like these i think pescetarianism is perfectly acceptable, but it's still not vegetarian.
