Sadly, it’s no surprise to see such a statement, the world is filled with people so indoctrinated with their own beliefs, especially in themselves, that opinions that seem acceptable to them, can actually be deeply offensive to others.
Right here in your answers, there’s an example. You have someone writing to dismiss the one whose initial comment gave rise to your question, with the throwaway line, “The Hubber ... seems to be a someone, who never finished High School. (sic) ....Remember. The Truth always Prevails”.
Whose truth? Speaking as someone who never finished High School, I find that statement both patronising and offensive. But I’m not holding my breath for an apology. As I said, the world is filled with the self-important, for whom a backward step is far too damaging to the ego.
But strident self-righteousness doesn’t necessarily equate to truth, in this instance from neither the Hubber who’s caused you concern, nor the one who’s insulted me.
