I stopped explaining myself when I realized other people only understand from their level of perception... and we are all on our level of learning so don't blame someone because they're below or above you - we're all learning as best we can... ;-)
That's why you don't need to confront people like that. Just walk away. They'll have the world believing you said things you never said. And to think that this sort of thing is learned before a kid even goes to school. Humanity is doomed.
