The idea of veganism at its core is quite simple: avoiding animal-based food products and products that test on animals. That is veganism in a nutshell.
However, veganism can be a lot more to some. Some vegans are activists. Many aren’t. Some vegans preach to others. Others do it for themselves (and the animals of course).
Veganism can be defined differently depending on who you ask but the above definition is the baseline to which veganism exists.
Most people think of veganism as a diet and not a lifestyle comprised of choices and decisions that expand well beyond one’s food preferences.
