Defending yourself against his words signals him that he can still manipulate you and he will keep it up for as long as you defend against him. Engaging in it will only boost his ego.

You know you are right and he will never agree with your point of view. If you stop reacting, he won't get his power fix. I get that it frustrates you and ticks you off. I suggest you crush boxes, or other such physical activity, to work through your anger instead of fueling his ego by engaging.

I crushed cardboard boxes and aluminum cans for a year to process anger. I was really angry, but it was very effective. His picture on a dartboard may help too.
