I try not to dwell on it, and I think it’s rude to comment on what people eat — I am not the sanctimonious type — but I think about it a lot. That’s probably why I keep writing about this stuff.

It’s not sanctimonious to comment on what people are eating if the intention behind it is not one of moral superiority but of concern for health. Whether it can be considered rude or not is another thing, of course. Many times non-vegans are the ones commenting on my food, and that is a great opener for me to engage in a discussion about it.
