I don't agree that it shows anything in regard to maturity, but you would be right about respect in a way - given the opportunities available to everyone in this country, anyone who can't master basic spelling (and I'm not talking about people who have the occasional difficulty, I'm talking about people who consistently spell badly) doesn't deserve to be respected for their spelling. They may indeed have many fine qualities for which they should (and no doubt will) be respected, but why would you respect something which is bad when it has the opportunity to be good?
