【Decry】 , 【depreciate】 , 【disparage】 , 【derogate】 , 【detract】 , 【belittle】 , 【minimize】 mean to write, speak, or otherwise indicate one’s feeling in regard to something in such a way as to reveal one’s low opinion of it.

【Decry】 implies open or public condemnation or censure with the intent to discredit or run down someone or something.

【Depreciate】 implies a representation of a person or thing as of smaller worth than that usually ascribed to it.

【Disparage】 implies depreciation by more subtle or indirect methods (as slighting, invidious reference, or faint praise).

【Derogate】 and 【detract】 (both with from) stress the idea of taking away, positively and injuriously, especially from reputation or merit; 【derogate】 from may be used with an impersonal subject only, 【detract】 from with either a personal or an impersonal subject.

【Belittle】 and 【minimize】 both imply depreciation, but 【belittle】 suggests an effort to make a thing contemptibly small, and 【minimize】 to reduce it to a minimum or to make it seem either disparagingly or defensively as small as possible.
