I just did a quick look at the most popular, admired, or favorable women of 2015. I checked three different random lists.
Michele Obama, Kim Kardashian, Nikki Minaj, Beyonce, Serena Williams, Mindy Kaling, Amal Clooney, Oprah Winfrey, Kim Kardashian, Rihanna, Ariana Grande — all of these were included in the top twenty of most lists.
Women of color do not dominate the list, though they generally split it pretty evenly with the majority white women.
Perhaps the perception that obnoxious, privileged, white women are disproportionately ruling the roost is merely the perception of this one writer. In my expereince, most white women are very reluctant to assert themselves, with anyone. My perception is true, or just my perception?
