Please, correct my essay.

The man says that some white supremacist group was trying to pass out racist leaflets on campus last week. Also, there’s a rumor that some students were handing out leaflets. When the campus police made them stop, they wrote an anonymous letter of protest to the President saying their right to free speech had been violated. The woman says that that is a difficult issue. However, she agrees with the President. Her example is s crowded theater. People cannot yell `Fire’ in a crowded theater and should be able to make racist or sexist comments in a class discussion.
