Who said that's why he does it? He is simply typing how he speaks and in a way he knows everyone can understand perfectly, it's 100% as valid and legitimate as your chosen means of communication. And referring to him as a backwards peasant betrays your true feelings, you look down on working class people it's undeniable, by your own words.
I think your complete lack of morals, honesty and decency as well as class puts him in a much better position to be looking down on you tbh, he's a better person than you.
