All harassment and actions that create a hostile environment based on gender identity or expression shall be prohibited.
The following behaviors may constitute evidence of unlawful harassment and hostile environment:
In determining whether there is unlawful harassment or a hostile environment, the totality of the circumstances surrounding the alleged violation of the Act must be considered, including the nature, frequency, and severity of the behavior, whether it is physically threatening or humiliating, or a mere offensive utterance; and whether it unreasonably interferes with the alleged victim. Ultimately the standard is an objective one, focusing on whether the behavior was sufficiently severe or pervasive to alter the conditions of the victim's employment, housing, education, or access to or use of public accommodations, or relations with a District of Columbia agency or contractor, and to create an abusive environment.
