Ah, I see. Thank you Mairead. I thought it was because the milk was an animal product.
Not so sure I follow all the thought processes of the different sorts of vegetarian ways of eating.
I know there was one young woman acquaintance who was a bit prissy about being a vegan... yet wore Italian leather shoes? Ummm... okaaaay...
The vegan professor I used to know didn't use anything at all, ever that came from an animal or was the result of profit from an animal. She was pretty rigid, but I respected her for knowing the source of everything she used and ate. A daunting task to be sure!
