Veganism is the ideas and underlying principles and beliefs as to why a person inevitably adopts a vegan diet. 'Vegan' only defines the type of diet.

Veganism has a commonality in principles, but is not exclusive, nor limited to the following;

Ethical - enabling animals to have rights to prevent torture, rape and murder of all sentient beings.

Environmental Sustainability - The impact animal production has on world. Ref. United Nations Report '07: Livestock’s long shadow.

Health - Global Famine, The shortening of life spans, and obesity ~ mainly heart related illnesses. Animal born Diseases, Athleticism.

People adopt some, the whole or no beliefs, yet are still vegans. The main point is that whatever path we have taken; it was a strong enough conviction to adopt a vegan lifestyle.
Q: How could you be a vegan, yet not believe in veganism?
A: Simple, by adopting the diet, yet rejecting the principles.

vegan comes from the word vegitarian.
a person who is vegan is someone who does not eat meat, dairy products, or eggs. vegans also do not wear clothes made from animal products. veganism can be more healthy then eating meat. 33% of teens are obese. 2% of vegans are obese. animal products are loaded with chemicals, fats, and byproducts that your body cant use and does not need.
I am vegan because i dont think that animals should have to die for my tastebuds.

The state in which someone deprives their self of anything that tastes good in an attempt to save an animal that is already dead.
The vegan wouldn't eat the cake, cookies, or brownies because it was exploiting the chicken that gave the eggs.

The vegan had to be hospitalized when they became stranded on a desert island and would only eat the microscopic supply of celery in their pocket. Stupid veganism....

A violation of nature. Humans, like other species, have evolved with the fortune of the ability to digest meat and vegetables, and this should be used. All the vegans seem to obsess over the lives of the fish that are caught and dried and sent as food to famine-stricken regions, and seem to not care that if they offered a carrot to a polar bear, it would devour them. But then again, maybe the bears are smarter.
Save a cow, eat a vegan.
End veganism!

A popular trend among the youth of today to not eat or use any animal products. What most of these trend following kids fail to realize is that many things they don't even know about contain animal products.
Many vegans like to hang out together and go get tattooed and pierced while listening to "hardcore" music and being "straight edge".
Most tattoo inks contain animal by-products.

Vegans will fade out as the next trend becomes popular.
There will be a great surge in the tattoo removal business.
I became a vegan because all my friends are!

The breathtakingly beautiful act of preforming anal in a decalcified browneye. As vegans do not consume meat, dairy, or eggs their colons move much faster and have no backlogs; providing a much more pleasant experience.
