I would be interested in a vegan & vegetarian community, but since vegetarian is a superset of a vegan diet, the combination would make the community effectively vegetarian. One of my favourite communities on reddit was r/vegan, where the discussions were usually much broader than just food-related, and on the other hand there was no need to look through delicious-looking food pictures to find out they were not vegan when looking for food. Hence, I would appreciate a specifically vegan community even more.
