It’s not something you actively use, it is just “there.”

For example: I applied to a job as a refrigeration technician and during the interview the guy actually fucking said “it’s really hard to get clean cut white guys to apply. I don’t want some Dominican (literally referring to their Dominican maintenance guy) walking into a store with our logos on.”

I had finished a tech school with some other black guys that I know also applied, I got the job and they didn’t. :/
