If race isn’t real, how can racism be? Seems like a reasonable question, but it’s like saying, if money isn’t real, how can we prosecute bank robbers? Money has no value on its own, but since it represents real things, or can be traded for real things, it represents “value” to us. Science has proven that race cannot be delineated, and is therefore objectively nonexistent. Race is socially constructed, and the classifications change over time and over geography, but because we recognize it as a real thing, we identify ourselves as members of a “race” for purposes of forming community and preserving tradition, and we can identify others as a “race” for purposes of exclusion, violence, etc.
