As it happens, when I had a discussion with that friend I wasn't talking as an author, but rather as a viewer of a film. We are discussing a female character in a recently released film.
The unusualness of the discussion comes from the fact that we both agree that the "damsel in distress" isn't desirable, and the female character should have strength. You were on the dot with "also human" there, because that's precisely what I was arguing about.
My friend thinks that in order to be a strong character, she should display no flaws or weaknesses. The flawlessness is definitely an issue, but that aside, I had a problem with what she called a weakness. Apparently forming bonds with a male character is a weakness. Apparently refusing a male character is strength. Apparently that first weakness mentioned there takes away from her later displays of strength, and I'm talking about defying authority for her belief and undermining a prejudice that has been in place for centuries. I admire that courage and can't accpet the fact that having a soft spot for someone automatically makes her ineligible to be considered a strong female character.
THAT, I had a huge problem with.
