"There are inherent problems in pairing sexuality with vulnerability." Straight from the article itself and I won't lie, I scratched my head at this.

I think some people correlate vulnerability with female characters too quickly and that's sadly because of the way female characters have been portrayed in the past. So when these two words are together in a sentence, it instantly makes people think that the character is going to become a Mary Sue.

And that is a horrible mentality to have.

The fact of the matter is that you can have a character be in a situation that makes them feel vulnerable and it will still be a good story. There's a sense of realism when a character is uncomfortable about doing something or making an immoral decision. It makes us feel like we're following in this character's foot steps and when done well we can relate with the character.

In short, I think that article writer should "calm their tits" and wait until the final product is released.
