Wearing a pressed gray suit, black shoes and a purple shirt and tie, Kameron Slade, 10, fidgeted slightly before his name was called in the City Council chambers on Wednesday. He approached the microphone set before the room full of politicians, lowered his head to the papers he clutched in his hands and began to speak. “President Barack Obama recently talked about same-sex marriage with his wife and two daughters. Some people are for same-gender marriage, while others are against it,” Kameron said. “Like President Obama, I believe that all people should have the right to marry whoever they want. Marriage is about love, support and commitment. So who are we to judge?” Kameron was invited by the Council speaker, Christine C. Quinn, to deliver his speech, which he wrote two months ago for a student competition at Public School 195 in Rosedale, Queens. The principal, Beryl Bailey, deemed it inappropriate for the school, so Kameron was at first not allowed to deliver his speech on the topic.
