The main reason is, if in middle age they needed medical service they will give their doctor this message killing them will not stop them from having kid. because they already have it
How to stop this circle:
For stopping this belief what doctors can do is not harming childless colored patients. If others in family and friend see a young (childless) colored person has received correct medical service, it changes this belief that as colored person for receiving correct medical service you need to be a family guy.
In anyway usually single/childless patients are young so they make very small portion of your patients, so killing them has little effect on population.
