Oscar winners spent the 88th annual Academy Awards speaking up for equality, whether that was Sam Smith devoting his best original song win to the LGBT community, best documentary short winner Sharmeen Obaid-Chinoy talking about the power of women working together, or the night’s numerous calls for Hollywood to recognize the work of more black actors and creatives in the field.

Ahead of the ceremony, Patricia Arquette — who won her first Oscar, for Best Performance by an Actress in a Supporting Role, at last year’s show — added to the conversation, offering a reminder that women still don’t possess equal rights to their male counterparts.

“We’ve got 33 million women and kids living in poverty in America who wouldn’t be if their mom was being paid there full dollar,” Arquette told EW on the Oscars red carpet Sunday. “But now we really need equal rights in America.”
