sexual orientation?
I think that student can make a complaint to the Office of Equality or to the Administration for a violation of antidiscrimination policy
Students have the right not to be discriminated against by any agent or organization of Syracuse University for reasons of age, creed, ethnic or national origin, gender, disability, marital status, political or social affiliation, race, religion, sex, sexual orientation, gender identity, or gender expression. In their individual roles as members of student organizations, students have the responsibility not to discriminate against others.
Or violation of code of student conduct:
"Harassment, whether physical or verbal, oral or written, which is beyond the bounds of protected free speech, directed at a specific individual(s), easily construed as "fighting words," and likely to cause an immediate breach of the peace."
These are policies at Syracuse University. Students and likely faculty there can report an incident to the Office of Judicial Affairs.

Your students, no matter what their orientation, race, or gender have a right to feel safe in the learning environment and not subject to publicly posted derogatory comments during instruction time.
