I interpreted "Kai is just a woman" as, regardless of the small amounts of fame that she's stumbled into, she still has wants and needs just like every other woman does. OP's post had no mention of whatever derogatory version of "just a woman" you're thinking about.
Also, the fact that there are people here virtue signaling about misogyny is fucking hilarious. No one knows you're browsing this forum. No one knows who you are and no one cares. No one's gonna be driving to work one day and think, "Hey, you know what? That guy on Simpcity was right. Maybe the words "just a woman" really does hurt a woman's chance at succeeding in this evil patriarchal society. I'm gonna change my ways and be more mindful while I'm browsing through women showing their buttholes on camera for $10."
Anyway, I'm not here to argue about misogyny so this'll be my last comment about this (but please, continue to attempt finding your moral high ground here so I can laugh at it. It's genuinely hilarious).
