There are any number of things you can do to express your thoughts about this situation.
(1) Contact any faculty members you might know at GSE. They face a very challenging summer. Ask them what kind of support they want or need.
(2) Contact Mary Watson. She is the head of Exceptional Children at the Department of Public Instruction. EC is the section that includes the Governor's School program. firstname.lastname@example.org or 919.807.3969
(3) Contact Tom Winton. He is the head of Governor's School at DPI.
email@example.com or 919. 807.3982
(4) Support any students you may know attending GS this summer. Allowing homophobia to shape curriculum, either explicitly or passively, sends a very dangerous message to any student who is thinking about his/her sexuality, feels alienated in any other way, or publicly identifies as queer, gay, lesbian, asexual, bisexual, transexual, or transgendered. All students at GS must be safe this summer to do the very hard intellectual and personal work the GS program demands of them.
