I dont see it here, so figured someone's gotta post it. Here is the definition of veganism as made by the vegan society circa 1944:
"Veganism is a philosophy and way of living which seeks to exclude—as far as is possible and practicable—all forms of exploitation of, and cruelty to, animals for food, clothing or any other purpose; and by extension, promotes the development and use of animal-free alternatives for the benefit of animals, humans and the environment. In dietary terms it denotes the practice of dispensing with all products derived wholly or partly from animals."
I think that line is important to explain that its impossible to completely wash our hands of any animal suffering, even as vegans, but I agree with your points that animals should given better rights (the first page or so of "animal liberation" by peter singer explains why the term "equal rights" is kind of unnecessary, but I know what you mean)
