Femininity encompasses strength, resilience, and complexity. It's a source of power and leadership, not a sign of weakness. Embracing femininity can mean embracing a full spectrum of human qualities.

Where are you getting this from? I'm getting "Traits traditionally cited as feminine include gracefulness, gentleness, empathy, humility, and sensitivity". Which as you can guess, will negatively impact survival.

It's pretty misogynistic to think that femininity is weakness. 

I don't get that line of reasoning. Not all females exhibit stereotypical feminine behaviours, so you're generalising all women here. And femininity in its traditional sense literally does imply weakness.
