What behaviours are acceptable in a relationship/friendship ?

About five months ago, I had an argument with a girl with whom I was friends with. In the past I had witnessed both kind and rude behaviour from her, the former being more frequent.

This argument began with her misunderstanding one of my jokes as something else and making a bad comment on me. When I questioned this behaviour, she said I can ignore it as she is not in the mood of taking anything lightly or thinking before speaking. I furthur asked her why she believes she can behave anyway just because of her mood, even if that means hurting others. She said maybe she is wrong but doesn't care about always being right, and that it's a side of him to be unapologetic whenever she is not in mood. She said I should stop talking to her if I don't accept this side of her. She said I don't have a right to complaint to her behaviour. And if I am trying to discuss about this issue, then I am trying to parent her.

Of course I ended the friendship, but still I am just confused if she really had a point, while me not understanding why I needed to accept her behaviour, or was I right in questioning and discussing about her behaviour? Does accepting this comes into accepting a friend/partner, and so you should tolerate any kind of behaviour from them just depending on thier mood ? Answers would be appreciated.
