For all of the hundreds of millions of tax dollars that have gone to Planned Parenthood, the organization is at least good for a laugh now and then.

Yep, the Women’s March on Washington was all about solidarity, once the organizers worked out those initial squabbles about race and intersectionality, whether Hillary Clinton should be added as an honoree, and clarified that, as long as they were prepared to listen rather than lead, men were welcome, but pro-life groups were not.

In retrospect, though, the march in the end was all about solidarity … with the exception of trans people and others who felt excluded because of the march’s focus on genital-based feminism. What’s important, though, was the people stood united under a shared fantasy of blowing up the White House.

The Women’s March has inspired a Scientists’ March on Washington, and the organizers are trying to steer clear of having to send those engraved invitations after the fact by making it clear that the march is open to “anyone who values empirical science. That’s it.”

However, there does seem to be some fine print attached: Organizers have declared there are “certain things that we accept as facts with no alternatives,” including anthropogenic global warming and evolution. Sorry, heretics.

It would seem a march predicated on hard science would be a cinch to pull off, but this march too is confronting questions of inclusiveness and diversity.

Wait, wasn’t valuing empirical science the only requirement to attend? This is getting tricky.

Dude, does Christina Hoff Sommers even own a lab coat? Seriously.

Organizers noted Thursday that inclusiveness also is a top priority, and the diversity committee is on it. The official website currently notes, “Science is done by POC, women, immigrants, LGBTQ, indigenous people, people of all beliefs and non-belief. We hope that this diversity is reflected in both the leadership of the march and the march itself.”

Too late.

Absolutely, focus on science while emphasizing diversity and acknowledging the intersection of societal systems of oppression. And make sure celebrated white male TV host Bill Nye is there with a slide show of photos he took of the weather report on his TV.
