i'm a fish and veggie person, mainly because i don't have the responsibility needed to supplement my diet. however, when i did try to eat only vegetables i never identified myself as "vegetarian." something about going to the trouble of labeling yourself over what you eat seems pointless to me. i feel the same way about straight edge. some people drink, some don't. some eat meat, some don't. i wouldn't feel like either label somehow defined me as a person, and find silliness in the need to do so.
on another note, i come from a very traditional italian family, so i've never been able to stay too far from dairy (cheeses) and on occasion i do now eat meat again because my dad/uncles make homemade salsiccia. unfortunately the latter gives me "digestive problems" because my system isn't used to metabolizing meat anymore. though i conversely have not eaten fast food in over 10 years.
