con⋅tro⋅ver⋅sy
[kon-truh-vur-see

–noun, plural -sies.
1. a prolonged public dispute, debate, or contention; disputation concerning a matter of opinion.
2. contention, strife, or argument.

A controversy is a dispute, argument, discussion or debate featuring strong disagreements and opposing, contrary, or sharply contrasting opinions about an idea, subject, group or person. A controversy can range in scope from private disputes between two individuals, such as claims to property, to large-scale disagreements between societies.

The term originates circa 1384 from Latin controversia, as a composite of controversus - "turned in an opposite direction," from contra - "against" - and vertere - to turn, or versus (see verse), hence, "to turn against."

A controversy is always the result of either ignorance (lack of sufficient true information), misinformation, misunderstandings, half-truths, distortions, bias or prejudice, deliberate lies or fabrications (disinformation), opposed underlying motives or purposes (sometimes masked or hidden), or a combination of these factors. - wiki
