Let's also note Kamala was unmarried until age 49. When she got married in 2014, she became stepmom to two kids.
Society pressures women to marry and have kids. The stereotype of a woman who is single and childless at 45 or 50 is "sad" or "unfulfilled" or that she must feel like something is missing in her life. I think Kamala serves as a counterexample of someone who was living a perfectly great, childless, husbandless life.
I'm reading a book about how the immense pressure on women to get married and have children (and the judgment toward women who don't) is part of the backlash against feminism.
