So saddened and disappointed to read this article, especially coming from someone I thought better of.
Veganism isn't something you dip in and out of. It's not a diet where you can have the odd 'cheat day'. It's a philosophy and way of life you either believe in and follow... or you don't.
Like being against racism. You can't claim to be anti-racist if at weekends you indulge in a little race-hate for light relief.
I recently wrote this article about people trying to redefine what veganism is. I suppose I should thank you, because you forced me to go back and edit it, which I think improved it. https://pathlesspilgrim.medium.com/vegans-stop-redefining-veganism-964d1fbda3c5
