A thesis that evaluates. A claim that inspires antagonism is a statement that expresses an opinion about the issue. It's a matter of opinion. It deems one topic to be superior or inferior to another. It has nothing to do with fact. Any opinion on a controversial subject will be viewed as prejudicial, even if it comes from an impartial source. An evaluation thesis is one that expresses an opinion on the subject. Evaluation theses are often not stated explicitly, but inferred by the writer. For example, when writing about music, a reviewer might say that a particular album is "bad" or "harmful" without actually stating an opinion. But this doesn't mean that it isn't an evaluation thesis; the writer is simply keeping quiet about it. Evaluation theses can also be implied by showing preference for one topic over another. For example, if a writer prefers English poetry to French poetry, they are implicitly asserting that one genre is better than the other. Again, this doesn't mean that it isn't an evaluation thesis; the writer is merely expressing an opinion. Writers use evaluation theses when discussing topics that don't have clear-cut facts or studies that can be referenced; instead, opinions are given based on personal experience or knowledge of others who are believed to be knowledgeable about the topic.
