As any sensitive and enlightened 21st Century man can tell you, "Dairy Queen" is a pejorative term used to describe a woman who chooses to nourish her child naturally. I'm sure that anybody with even a shred of decency can agree that that insulting term has no place on a roadside ice cream stand.
In fact, Sam Adams, that recent ruling by the Supremes in the case of Hindenburg (or somebody) also means the “Queen” in the name and logo is obnoxious and illegal.
Plus, as all good vegans know, dairy is verboten.
