Allowing Hate Speech Discourages diversity  Members of groups that find themselves the targets of hate speech will be less likely to attend universities where they feel targeted. As a result, those campuses will become less diverse which will decrease the most effective deterrent of hateful ideas: understanding through interaction. Less Muslim, gay, Jewish, etc. students on campus is exactly what those promoting hatred are trying to achieve. Less students of the targeted group makes them easier to target because there are less people speaking out against the hate speech. A downward spiral is created that, if not checked, can drastically reduce campus diversity which is a massive harm to social integration and social harmony. Speech codes or other censorship sends a signal to minorities that they are welcome in the university.
