Veganism means something different to each person.
Vicky was given lots of information and had support offered to her and still made the choice to leave veganism to become a vegetarian.
Only she knows why.
These actions do not make sense to many people who are passionately vegan for health, AR and environmental reasons and repulsed by even the thought of leaving veganism behind for any reason.
I undesrstand feeling confused as to why anyone would do this, and I think that this is where you are coming from by starting this thread; however, to some, it could look like a "shaming" of Vicky for her choices and if that is the case, I cannot support that...
If you are curious about her unique reasons, I suggest you ask her directly. She may or may not choose to be direct with you, but would likely be more open to it than after reading the opening of this thread.
So, I just wanted to give you a little perspective because I am trusting your intentions are in the right place-to educate and reach out- and I am in full support of that
