I think what people say is way more important than how they spell it. People may struggle with spelling for many reasons, they could have dyslexia or they may have had certain issues in the education system- any sensible person will understand that.

PS I struggled with spelling much of my life owing to a now discredited teaching technique used when I was learning to read, it was called ITA - in adulthood I feel a sense of kinship with those who went through the same teaching system.
