Carried her unprotesting out the door.
This is a bizarre line which becomes less bizarre if we suppose that there were times when she was carried out “protesting.” If someone is carried out of a door protesting, it’s reasonable to assume they were “kicked out.” So, this could refer to a home she was kicked out of, or a bar or club. Either way, this isn’t the first time she was “carried out the door,” but it is remarkable as she is not fighting or protesting the decision. She was a vibrant, feisty spirit whose quietness in death the speaker seems to find outrageous, impossible.
