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.
