What is being vegetarian/vegan – and what is the difference?

from wiki:

Vegetarianism is the practice of following a plant-based diet including fruits, vegetables, cereal grains, nuts, and seeds, with or without dairy products and eggs. A vegetarian does not eat meat, including: red meat, game, poultry, fish, crustacea, shellfish, and products of animal slaughter such as animal-derived gelatin and rennet.

Veganism is a philosophy and lifestyle whose adherents seek to exclude the use of animals for food, clothing, or any other purpose. Vegans endeavor not to use or consume animal products of any kind. The most common reasons for becoming a vegan are human health, ethical commitment or moral conviction concerning animal rights or welfare, the environment, and spiritual or religious concerns. Of particular concern to many vegans are the practices involved in factory farming and animal testing, and the intensive use of land and other resources for animal farming.

There are a number of vegetarian diets. A lacto-vegetarian diet includes dairy products but excludes eggs, an ovo-vegetarian diet includes eggs but not dairy products, and a lacto-ovo vegetarian diet includes both eggs and dairy products. A vegan diet excludes all animal products, such as dairy products, eggs, and usually honey. Many vegans also seek to avoid using any other animal-derived products, such as clothing and cosmetics. Vegetarianism may be adopted for ethical, health, environmental, religious, political, cultural, aesthetic, economic, or other reasons.

Semi-vegetarian diets consist largely of vegetarian foods, but may include fish, poultry, dairy products, and eggs. Followers of these diets may define “meat” as mammalian flesh. A pescetarian diet, for example, includes fish but no meat.[4] The common use confusion between such diets and vegetarianism has led vegetarian groups such as the Vegetarian Society to note that such fish or poultry-based diets are not vegetarian, because fish and birds are animals.

Properly planned vegan diets are healthful and have been found to satisfy nutritional needs, and may offer protection against heart disease, cancer, and other diseases. Poorly planned vegan diets can be low in levels of calcium, iodine, vitamin B12, iron and vitamin D. Various polls have reported vegans to be between 0.2% and 1.3% of the U.S. population, and between 0.25% and 0.4% of the UK population.

blah blah blah… ok, so now we know what they actually mean and I can stop guessing what exactly qualifies. I dont want any parts of either one of these lifestyles, and its not because I am some tough guy and think its pussy to say that I am either, but I just don’t see the need for it. None of our great grandparents were these things and they lived long and happy lives and seemed to get along fine. Where we have messed up is that we have taken things a little too far. There is no need for the Outback Steakhouse size servings that we are getting, and there is absolutely no reason that a medium drink at a local fast food spot now is the same as what an extra large used to look like. Becoming vegetarian is typical of us going to the other extreme. I don’t need to cut everything out I just need to get my sizes right. and stop going to fast food places and super sizing. and stop going to restaurants that use bad products and don’t give us nutritional values.
