America Ferrera, Scarlett Johansson and Madonna are taking a stand.
All three women took the stage to deliver speeches at the Women's March on Washington in the nation's capital on Saturday, just one day after President Donald Trump's inauguration.

A crowd of over 500,000 people showed up to participate in the event -- expected to be the largest inauguration-related protest in U.S. history, according to The New York Times -- to advocate for the rights of women, minorities and the LGBTQ community over the course of Trump's administration.
Ferrera, who serves as the event's Artists' Chair, kicked things off with an impassioned speech, claiming that we are all "under attack."
"It's been a heartrending time to be both a woman and an immigrant in this country," she said. "Our dignity, our character, our rights have all been under attack, and a platform of hate and division assumed power yesterday. But the president is not America. His cabinet is not America. Congress is not America. We are America. And we are here to stay."
"We march today for our families and our neighbors, for our future, for the causes we claim and for the causes that claim us. We march today for the moral core of this nation, against which our new president is waging a war. He would like us to forget the words, 'Give me your tired, your poor, your huddled masses, yearning to breathe free,' and instead, take up a credo of hatred,"

Johansson, meanwhile, used her speech to address Trump himself.
"President Trump, I did not vote for you. That said, I respect that you are our President-elect and I want to be able to support you," she said. "First, I ask that you support me, support my sister, support my mother, support my best friend and all of our girlfriends, support the men and women here today that are anxiously awaiting to see how your next moves may drastically affect their lives."
"Support my daughter," she continued, "who may actually -- as a result of the appointments you have made -- grow up in a country that is moving backwards, not forwards, and who potentially may not have the right to make choices for her body and her future that your daughter, Ivanka, has been privileged to have."
The actress then focused her speech on advocating for Planned Parenthood, and how its facilities have helped her and saved the lives of her friends.
"No judgment, no questions asked, Planned Parenthood provided a safe place where I could be treated with gentle guidance. Now, I may have been 15 and surprisingly self-sufficient, but I bet there isn’t one person here who has not been helped by Planned Parenthood, directly or otherwise," she said. "There are very real and devastating consequences to limiting access to what should be considered basic healthcare."

Madonna then gave a slightly more charged speech, delivering a "f**k you" to detractors of the movement.
"Welcome to the revolution of love, to the rebellion, to our refusal as women to accept this new age of tyranny, where not just women are in danger but all marginalized people, where being uniquely different right now might truly be considered a crime. It took this horrific moment of darkness to wake us the f**k up."
"To our detractors that insist that this march will never add up to anything, f**k you," she said, before insisting that this protest was just "the beginning."
"I have thought an awful lot about blowing up the White House, and I know this won't change anything. We cannot fall into despair," she confessed, before stating the she would "choose love," and performing "Express Yourself" and "Human Nature" -- the latter of which she dedicated to Trump.
