If you're a Vegan then you really shouldn't be eating honey since eating honey goes against what a Vegan stands for.
Vegans are not supposed to eat anything derived from animals or insects.
And honey is derived from insects so a Vegan should avoid eating honey.
Although there's no law that says a vegan can't eat honey so if a Vegan wants to avoid other things derived from animals and eat honey then you could still be a vegan in other ways but only eat honey.
