Ummmm, I think the peas are allegorical. She wrote about her distaste for peas and asked if it changed our opinion of them.
She's an author that some critics have severely criticized, also apparently on a personal level. She wants all of us to be more considerate when we offer an opinion. She writes that words "are capable of uplifting, positive thoughts or negative, hateful ones. ...if they are written with the sole purpose of shredding someone to the bone, it only takes a few sentences to flay someone." She asks us to, "Try to remember that before you write or speak something negative today."
I agree with Muebe, "Just a fantastic article!"
