White women only care about "womanhood" when it something that negatively affects their lives. Now that abortion has been banned, now they care! When women of color need help, or a hand, or even a word of affirmation, white women (at least the ones in the US) are always silent. For example, the numerous times that Black female entertainers have been run off social media by bigots, while white women either remain silent, or actively participate in it themselves.
We don't ever hear them speak up when it comes to the treatment of Indigenous women, the stereotypes perpetuated against Latinas and Asian women, and the disrespect levied at Black women. In fact, more than a few of them are willing to participate in the behavior just to increase traffic on their social media!
