She didn't make the choice to look like a blowup doll in a vacuum. There is a culture and a society that encouraged, maybe even necessitated that she look that way in order to succeed, and she nodded her head and conformed. Make her the victim though, if it works that way in your head, I suppose. She is just another female who stayed well in her lane yet tries to act above everything.
If we're being 100, the real feminist in hip hop is Missy. She never enticed the male gaze ever nor did she ever berate women.
She gave great visuals without selling sex but then again it's not like she really could if she wanted to.
Lauryn Hill, Salt n Pepa, and Queen Latifah before that. Kim and Nicki are not what I consider feminists esp Nicki
