Here's an example of a sentence using "interracial" in a neutral context:
The film explores the challenges and triumphs of interracial couples in the 1950s.
However, it's generally better to avoid using "interracial" if possible and instead use more specific and descriptive language, like:
The film explores the challenges and triumphs of couples from different racial backgrounds in the 1950s.
This phrasing avoids the potentially problematic implications of "interracial" while still conveying the intended meaning.
