Explanation

To be anti is to be opposed to or against something, like an action, political party, or government. If you are anti love scenes, you might prefer an action flick. The word anti comes from the prefix anti-, which means “against” or “opposite,” and is still used in English words, such as antibodies and anti-hero. As a word on its own anti is an adjective or preposition describing a person or thing that is against someone or something else. In a casual sense anti is sometimes used as a noun for a person who is against something — if you’re not on the pro side, you’re an anti.
