According to who?
But it was quite clear that the definitions are not claiming to be universal, otherwise they wouldn't have the terms 'we define' or 'for the purposes of our membership' etc. That is the case with the above - for the purposes of membership of the IVU eating fish is considered a form of psuedo or non-vegetarianism.Unless you listen to some people who are pseudo-vegetarians who by their definition are vegetarian yet clearly aren't. My counter to your point being that despite the fact that I have provided multiple definitions you keep coming back with the fact that they're not universal
I could start up a vegetarian society that had it's own definitions that said roast chicken, when done with proper roast potatoes in goose fat, was 'for the purposes of our membership' vegetarian. That doesn't all of a sudden make it universal
We agree on the broader points, and the fact of the matter is that that most people who do not eat a large proportion of the meat products out there will for convienience describe themselves as vegetarian. It's just the easiest and most accepted way of doing things.
Maybe I should describe myself as a sustainable-ecologically sound-low pollutant-thoughtfull stewardship-low distance-season-low instensive-demand lowering-not-asking-other-people-to-change-arian.. but that's just too much of a mouthful when 'vegetarian' meets 99.9% of my needs.
Infact I'd argue the majority of vegetarians disagree with the IVU's definition as well, especially with regard to by-products such as leather.
