The Women’s March on Washington on Saturday is set to be huge, drawing more charter bus permit applications than the actual Inauguration Day — of President Donald Trump — it’s protesting and more than 220,000 committing to going on Facebook.

In fact, the protests look to be so big that currently airplanes full of women are flying to Washington, DC, to join the demonstrations. Here are some of the images posted on social media so far:

You may notice from the pictures that the participants are largely white. At least some of the march’s supporters have acknowledged as much, like Ann Friedman on Twitter:

Yes, the women on this plane are overwhelmingly white. I noticed that, too. I hope tomorrow's march is as diverse as its leadership. — ann friedman (@annfriedman) January 20, 2017

This has been a frequent point of tension for feminist movements in general: the idea that they often seem to include only white women.

But the Women’s March has tried explicitly to break this mold, Jenée Desmond-Harris explained for Vox:

[B]y “women’s rights,” organizers have taken care to make it clear that they mean all women of all backgrounds: The official platform the Women’s March on Washington released Friday places the demonstration in the context of not only suffragists and abolitionists but the civil right movement, the American Indian movement, and Black Lives Matter. Just two paragraphs into the four-page document, they note that “women have intersecting identities and are therefore impacted by a multitude of social justice and human rights issues.” Examples of this, including the especially urgent need for equal pay among women of color and the way they’re uniquely victimized by the criminal justice system, follow in the rest of the platform.

Still, it remains to be seen whether the more inclusive message will translate to a more diverse audience.
