Something is getting lost in translation - Google, brother.
Vegans don't eat dairy, but vegetarians can. Vegetarians just don't eat meat.
Btw, I'm neither vegetarian or vegan. I am not buying dairy, though, for the reasons that most vegans won't. So, to find a non-dairy butter product, it's easier just to search for "vegan butter." I might eventually become a vegan, but I'm not there, yet.
