Besides a change food intake, what else is commonly involved in being vegan?

Many vegans, especially those taking on a vegan diet for ethical/moral reasons, will feel strongly about animal rights and welfare, and will often actively support and campaign on issues relating to animal welfare.

Crystal/Frostfire of Vegan Fitness submits a definition, found in a poem, for a vegan:

"Though it is commonly portrayed and perceived as nothing more than a diet that excludes animal products, veganism is an ethical philosophy that rejects the commodity status of ALL animals (including bees whose food we steal only to burn them alive afterwards and silkworms whom we boil alive for their silk), not just "food" animals. Vegans are against the enslavement, exploitation and killing of animals for food, entertainment, clothing, cosmetics, experimentation, etc. purposes; veganism is about animal liberation."
