An anti-Trump protest scheduled for after the inauguration is expected to draw approximately 150,000 attendees.

Or not.

The "Women's March on Washington," which started with a single Facebook post, is experiencing some intense infighting over ideological purity, according to The New York Times.

A few women have gone so far as to cancel their plans to attend the demonstration in Washington, D.C., claiming identify politics have made them feel unwelcome.

Basically, some would-be attendees told other would-be attendees that they are not ideologically pure enough to appreciate the dangers posed by the incoming Trump administration. So now one group of would-be attendees feels marginalized by another group of would-be attendees.

It's as confusing as it sounds.

A white woman from South Carolina said she canceled her plans to go to the march after one volunteer, a black woman from Brooklyn, posted a message on the group's Facebook page saying white people should talk less and listen more.

"Now is the time for you to be listening more, talking less," ShiShi Rose, 27, wrote. "You should be reading our books and understanding the roots of racism and white supremacy. Listening to our speeches. You should be drowning yourselves in our poetry."

The South Carolina woman, Jennifer Willis, told the Times that she found Rose's post to be self-righteous and annoying.

"The last thing that is going to make me endeared to you, to know you and love you more, is if you are sitting there wagging your finger at me," she said.

The 27-year-old Brooklyn blogger, however, defended her post, and told the Times that it wasn't meant to offend. Rather, Rose explained, it was meant only to say that white women have a lot to learn.

"I needed them to understand that they don't just get to join the march and not check their privilege constantly," she said.

Another black feminist posted a quote that called on attendees to think about "confronting the ways women — through sex, class and race — dominated and exploited other."

The Times report added:

A debate then ensued about whether white women were just now experiencing what minority women experience daily, or were having a hard time yielding control. A young white woman from Baltimore wrote with bitterness that white women who might have been victims of rape and abuse were being "asked to check their privilege," a catchphrase that refers to people acknowledging their advantages, but which even some liberal women find unduly confrontational.

The demonstration's organizers recognize that there are divisions in their ranks. But they say they're not worried about attendance numbers. Plus, they argue, rancor is a good thing.

"If your short-term goal is to get as many people as possible at the march, maybe you don't want to alienate people," said Anne Valk. "But if your longer-term goal is to use the march as a catalyst for progressive social and political change, then that has to include thinking about race and class privilege."

Oh boy, oh boy.

If this is what resistance to the Trump administration looks like, it's going to be a long, miserable four years for everyone.
