You really must be some dumb libtard, blathering on about the non-existence in 'science' of some word which you deem inappropriate or offensive or whatever other silly notion you associate with it.
If you'd read up a bit about taxonomy, you'd find the term 'race' is being used in biological sciences.
It's a taxonomic rank below subspecies, even if used informally.
Now please go back to your libtard snowflake group sessions on facebook with your retarded pseudo-science.
