Here's why:
* Adverbs modify verbs, adjectives, or other adverbs. They describe how, when, where, or to what extent something happens.
* "Racist" is an adjective. It describes a noun, such as a person, policy, or action, as being based on or reflecting racial prejudice.
For example:
* Adverb: "He spoke loudly about the issue." (Loudly describes how he spoke.)
* Adjective: "That was a racist remark." (Racist describes the remark.)
