I just found out there are flexible vegetarians out there. They’re called flexitarians. Wiki has this quote:
In 2003, the American Dialect Society voted flexitarian as the year’s most useful word and defined it as “a vegetarian who occasionally eats meat”. None of the vegetarian organizations recognize “semi-vegetarianism” as a category of vegetarianism, and it is viewed by many vegetarians as being paradoxical, like the terms “pesco-vegetarianism” and “pollo-vegetarianism“, since per definition a vegetarian diet does not include the flesh of animals.
Now I know I was wrong. Vegetarians can be open minded and dialectical!
