Being vegan is not a matter of "lifestyle." It is a matter of fundamental moral obligation. Is being vegan a matter of "choice"? Only insofar as we are able to choose to ignore our moral obligations not to exploit the vulnerable.
People need to be educated so that they can make intelligent moral choices
If you care about animals, there is one and only one choice: go vegan. Can you choose not to be vegan? Sure. You can choose not to care.
The distinction between meat and other animal products is total nonsense. Vegetarianism is a morally incoherent position. If you regard animals as members of the moral community, you really don’t have a choice but to go vegan.
