A regulation of speech on a particular topic in a nonpublic forum may not limit the speech to one position, to the exclusion of other positions. This rule reflects the fact that such a regulation must be Viewpoint neutral.
Step-by-step explanation:
There should be a regulation of speech about a topic or an issue in a non-public forum or limited public form. These regulations must be in such a way that it must be viewpoint neutral. It must give importance to the matters of both the sides.
It should not include the matter that is presented by one side and ignore those that are presented by the other side. When there is a regulation that focuses on the matter subjectively and the viewpoints then it is known as content neutral.
