With all due respect, I disagree. A vegetarian who almost completely follows their diet, is in my opinion a vegetarian the same way as a vegan who almost completely follows their diet is in my opinion a vegan. Why? 1) Defeatist approach (perfectionism) does not work 2) What matters is how the person identifies 3) There are hurdles to overcome when going vegetarian/vegan. These can be related to health, financials, logistics/availability, social situations where an exception could be made, the environment which can be at odds. Should anyone be interested I can give ample amounts of examples for each of these.

> I'm sorry but you shouldn't call yourself a vegetarian.

I understand your point, but I don't entirely agree. I think if someone's primary diet is vegetarian, calling themselves that isn't unduly misleading even if they eat meat on occasion.

But it may be a difference between being "vegetarian" in terms of participating in a movement and being "vegetarian" just because you prefer to eat that way.

I'd have to agree. She has a plant-based diet, but "being" a vegetarian is an ethical stance against animal meat for food. She could also say, "my diet is primary vegetarian", which moves the position from her to her diet choices.
