Most core communists tend to be utter and complete psychopaths, but the good thing about this is that they are receptive to statistics on race.
You can point out to them that no economy or economic system can produce anything looking like success when a large part of your population is sub-80 IQ. Hence they should oppose large-scale immigration.
The psychopaths want to be big and strong and successful, and they would feel bad if they would become unable to.
