There’s not a better retaliation to Donald Trump’s inauguration than a much larger crowd of detractors marching in the exact same place a day later.

That’s what the Women’s March on Washington, D.C., is becoming. In Washington alone, the numbers who’ve shown out for the march on the National Mall have already outdone the attendance for Trump’s swearing in. And it’s still building.

Hundreds of other marches all across America and the world are in direct retaliation to Trump’s non-inclusive message, and if there’s anything that makes him angry, it’s feeling small.

Organizers say the event’s primary focus is to promote equal rights for women and to defend other groups who are marginalized.

“The Women’s March on Washington will send a bold message to our new government on their first day in office, and to the world, that women's rights are human rights,” the group’s website says.

There are 673 official sister marches with more than two million additional people estimated to be participating. The marches are obviously showing that The Donald’s election is not a mandate and that hopefully any bigoted action coming from his campaign will be met with heavy resistance.

Twitter is flexing with pictures of the crowd sizes. Most are in Washington, however crowds in St. Louis, New York, Denver, Boston, London, Brussels and Paris look to be enormous. Check out some of the biggest crowds below.
