"It's not proper English."
"Is the purpose of language to aid in communication, or must it also be another control mechanism in our prison culture?"
"It's not proper English; and people think you're dumb when you say it."
"Do you really think use of 'proper' English is an accurate criterion for judging a person's intelligence? It may be a clue or an indicator; but one has to take it in context.

Or perhaps that's just the way they learned how to talk and don't feel the need for abject rule-following in communicating effectively."
