No, generally speaking, people agree in abstract terms on what virtuous principles are, such as honesty and courtesy; they disagree about what virtuous acts are, because in every act we resolve a conflict between conflicting virtuous principles, necessarily subordinating lower values to higher ones.
So you are saying ESR has a conflict between a virtuous principle which led him to use obscene language (is that autonomy?) and the upper class virtuous principle of courtesy, and he's subordinated courtesy because he's working class?
The GP said it already. The example virtues are honesty and propriety. If you value honesty over propriety, you'll speak honestly at the cost of speaking politely. If you value propriety over honesty, you'll either not speak or speak in a more polite/roundabout way to avoid conflict, even at the cost of honesty.
