Transgender activist and model Geena Rocero is supporting Emma Watson and her definition of gender.

During a speech Watson made at the United Nations on Saturday, she said, "If we stop defining each other by what we are not and start defining ourselves by what we are, we can all be freer..."

Rocero, who spoke during the 2014 Social Good Summit on Monday, said she "couldn't agree more" with the actress.

"Gender is a spectrum," she said.

Something happened when we, as a culture, created the mandate to put sex on the birth certificate the moment the baby was born. As much as I understand the purpose of it, we've confused that genitalia is always the same as gender. We've been led to believe gender is binary — either you're just a rigid male or female ... The transgender experience is a bridge that will connect the understanding of struggles and suffering of the rigid gender binary. Gender and gender expression is fluid.

But Rocero has hope that anthropology and technology can help to "eradicate gender suffering" so that it will not stand as an issue by 2030.

Rocero, who has been a successful model for more than 10 years, gained viral attention when she gave a TED Talk in March about her past and coming out as transgender. The talk has more than two million views as of this writing.

During the Social Good Summit, she commented on the TED Talk, saying it allowed her to "connect to the depth of my fear, own it and make sure I am not paralyzed by it."

Rocero also spoke about her experiences in the transgender beauty pageant in the Philippines, where she was raised, and starting Gender Proud, an organization to advocate for rights of transgender individuals — a cause she became interested in after having security issues traveling with her passport that identified her as a male.
