About Category:Communist terrorism and related categories
The scope of this category includes pages whose subjects relate to terrorism, a contentious label.
Value-laden labels—such as calling an organization and/or individual a terrorist—may express contentious opinion and are best avoided unless widely used by reliable sources to describe the subject, in which case use in-text attribution. Avoid myth in its informal sense, and establish the scholarly context for any formal use of the term.
