There seems to be so many different levels of vegetarianism, I tend to get confused.
So, as a vegetarian, where do I stand ? Well, taking the "if it involves killing then its verboten" as a given, personally I see no fundamental problem with eggs, milk and such bearing in mind that in an ideal world the animal is getting both life and looked after in exchange.
However, I did say ideal world (ok, vegetarian ideal world). "life" and "looked after" is just so far from the reality of the vast majority of farmed animals that for me personally eggs too should be verboten for any vegetarian for who the driving force is animal welfare (like me) as opposed to those whose motivation is health or environment.
But I feel I have to compromise. I won't buy eggs, I wont buy directly egg products (egg noodles, scrambled egg, so forth) but there are times when indirect products are acceptable to me as a compromise, usually when having to mix with friends and family who are mostly meat eaters. For example, Quorn "chicken" roast at Christmas. There are also instances of products that are labeled vegetarian but I can't work out why they wouldn't also be vegan based on the ingredients list. Presumably traces of egg/milk derived products, so presumably yet again I'm compromising.
But the bottom line is, my compromises have meant that I haven't knowingly strayed from from the straight and narrow after all these years and I suspect if I had tried to go the whole hog then I wouldn't be here in this forum now.
PS : I don't like my dependency on milk either, but until soya alternatives are _readilly_ available in sizes where I don't have to throw 80% of it out because I can't use it up fast enough then again I've had to compromise.
