Everything I’ve ever listened to of yours you were loud, bombastic, agressive and self-righteous. If that carries over into other personal interactions, I imagine some of the smarter more introverted people keep quiet instead, as they aren’t afforded the room to speak their mind because you’re talking over them with your presumed “I know what’s best” attitude. Since you’re the only one giving an opinion at length it doesn’t mean no one else has added value on a subject. They just don’t feel like wasting their time or energy on a know-it-all.
