Which word describes someone marked by a strong opinion about a controversial topic?

The term "tendentious" is employed to describe someone who has a strong, often biased opinion about a controversial topic. When a person is tendentious, they typically advocate for a particular perspective and may present their arguments in a way that promotes a specific agenda. This inclination can result in a one-sided understanding of the issue at hand, as the individual is more focused on supporting their viewpoint rather than considering opposing arguments or evidence. On the other hand, the other words provided have differing implications; "ambiguous" refers to something that is open to multiple interpretations, "objective" denotes a neutral stance free from personal bias, and "impartial" signifies fairness and lack of favoritism. Each of these terms contrasts sharply with the strong opinionated nature associated with being tendentious.
