We have a sizable and growing collection of questions that explore the fringes of veganism. All of these questions have one thing in common: they're about products that have been contaminated or adulterated in a way that would cause some vegans to see them as impure, but there is no tag to describe that connection.
The community previously decided on meta that questions about what is/isn't vegetarian or vegan should not be allowed on this site, but it appears that consensus never carried through into practice because many of these questions were left open. As long as we are permitting them on the site, I think we should also try to provide them with structure. Even people who perceive these questions as low value could stand to benefit from introducing appropriate tags, because then they could be excluded from view.
Currently all of these questions are tagged with veganism, but for many questions that is the only tag that has been used. A few are also tagged with animal-by-products, but that tag has no guidance and the phrase "animal by-products" actually means different things in North America and Europe. I think we should come up with guidance on how to tag these questions going forward (and retroactively).
What tag(s) would you use to group these questions?
Here is a non-exhaustive list of questions that explore the edges of veganism, grouped together roughly based on the means of adulteration specified by the best answer.
These questions are about products that are supposed to be vegan, but may have inadvertently come in contact with animal products at some point. Any adulteration, if it occurs at all, is not required and does not fundamentally change the product. In practice this is generally not an ethical concern for vegans, but it may affect people who are vegan for health or allergy reasons.
- Can products labeled as "produced in factory that handles milk" be considered vegan?
- Traces of non-vegan ingredients
- Do some vegans avoid using cookware that's previously been used to cook meat?
These questions are about products where animal parts temporarily come in contact and are later removed, such as catalysts and filtering agents. Very little (if any) animal remains are left in the final product. Bone char is a common example here. This is not generally a concern for people with allergies, but some vegans may have an ethical concern.
