(e) This section does not prohibit an institution from adopting rules and regulations that are designed to prevent hate violence, as defined in subdivision (a) of Section 4 of Chapter 1363 of the Statutes of 1992, from being directed at students in a manner that denies them their full participation in the educational process, if the rules and regulations conform to standards established by the First Amendment to the United States Constitution and Section 2 of Article I of the California Constitution for citizens generally. (f) An employee shall not be dismissed, suspended, disciplined, reassigned, transferred, or otherwise retaliated against solely for acting to protect a student engaged in conduct authorized under this section, or refusing to infringe upon conduct that is protected by this section, the First Amendment to the United States Constitution, or Section 2 of Article I of the California Constitution.
