AIUI “vegetarian” in India usually excludes eggs. This likely means that a _majority_ of the world’s vegetarians do not eat eggs.
> This is basic stuff; has someone been trying to redefine "vegetarianism" recently?
Oddly enough, when the word was introduced to popular use in English (though note that similar _concepts_ predated it), it usually meant something closer to what ‘vegan’ does today. The current use of the word is a 20th century thing. Words get redefined, all the time; that’s how languages work. Deal with it. In this case, the word has generally tended to be defined in _more_ permissive terms, not less.
