There is nothing to defend. You are in the christian debate forum. If you say that someone does not have the right to believe the way that they do, then what right do you have to say what you believe either?
This goes much deeper than someone disagreeing in the bigger scheme of things.
You keep playing the game with him. There is no justice here for what you are seeking.
Please remember that you are not the only one he has said things about...but you don't see any one else stating that this is a TOS issue....this is a belief issue...just as if you stated something against homosexuality. Do you want TOS to rule over your right to speak against it? This is matter of someone pushing your buttons and you are letting them bother you. Don't play the game.
You are the only one that can stop taking it personal...If it's not true...then don't react to it. Your character is still intact with God.
