In a manner that opposes racial discrimination or rejects racial divisions.
From antiracial + -ly (adverbial suffix). Combines anti-, racial, and the adverbial -ly to create an adverb describing actions or positions taken against racism.
This adverb is rarely used in modern English, which tells us something interesting: we tend to use 'antiracism' (the noun) and 'antiracist' (the adjective) instead, suggesting that how we talk about social movements changes over time.
