Repeat after me, folks: romantic plotlines don’t ruin female characters.
A female character isn’t weak because she has normal human emotions. She isn’t anti-feminist because she has vulnerabilities. There’s a difference between a female character existing entirely to be in love with the male character and a female character who happens to have a romantic subplot as part of her story.
It isn’t feminist to insist that female characters have to be “badass” unfeeling robots, detached from absolutely anything considered “feminine,” including, apparently, emotions. Sure, we don’t want female characters to be damsels in distress, but swinging in the other direction, to cardboard-cutout-badass-making-quips, isn’t much better. Good female characters appear human. And sorry, romance-haters, but love is a part of that.”
