The mother of three said she does not want her kids to be bullied by anyone, reported E!Online.
"I have three little kids that I hope grow up to be just as inspired to speak out in what they believe in and what their friends believe in," she said.
Roberts, 46, is impressed by the teenage gay rights activists she met on at GLSEN's Respect Awards.
"These are the heroes, what they deal with, how brave they are, how well spoken, how articulate, the way they champion themselves and their causes is incredible to me. I was not like this when I was in high school," she said.
