https://vegetarianism.stackexchange.com/a/1125/861 - Based on this classification of Veggie types (and maybe more types), would it not warrant equal privileges and filtering & tagging capabilities to all Subsets & the Superset to be accessible?
If "vegans" and "lacto-ovo" classes have the benefit of tagging their questions & posts, as well as the ability to filter/ search as per those tags, why not have tags for other classes as well? i.e. Laco-veg and maybe posts that are meant for "superset" Vegetarian so as to specify that this does not go a "vegan" or sub class way when a question is intended towards Superset and not subset.
Give us the Lacto-veg tag / category for our subset.
Why should we not able to "direct" a question towards a Superset "Vegetarian" when we can direct it towards a subset "vegan".
