Well, you kind of painted the picture of the man you married when you said: He knows better how to raise anyone
else's kid than they do. This is very arrogant, but I
know the type. What he doesn't know is how to raise your
14 year old. Unconditional love is not earned, it is freely
given, oftentimes with sacrifice from the giver. However,
respect is to be earned and he is going about it the wrong
way. I'm afraid that you may lose the respect of your daughter also if you don't bring some sense to this man. How you do it? Wow.
I'd say a prayer each time I would address him. "God, please give me the words to say, the patience to say it and the right timing to say it, and please help "him" be receptive and listen to my feelings." You've gotta have a rule to listen to each other until you've finished your thoughts. You've gotta give respect in order to receive it. His PERCEPTION is wrong according to the "well-intentioned" description of your daughter. He thought she slammed the door on purpose. If he really wants her to learn how to close the door, he could remind her to close it gently at the time she is getting out of the truck.
He needs to model the behavior patiently for her to be a
willing participant.
Sounds like he's in a habit of responding a certain way
with her. His reaction to her is "a choice". He is on auto-response. He needs direction, badly. Dr. Phil: "You
can't change what you won't acknowledge". Also, Dr. Phil
would say about your husbands style and appropriate manner
of discipline is "How's that working for you?"
PERCEPTION is a funny thing. It is different for everyone
but it is "their perceived truth".
I wish you the very best and truly hope he is receptive
to changing his ways.
