There should be community awareness programs. Neighbors or local organizations could approach the family in a non - confrontational way to educate them about the harm of racism. Social services might also get involved if the situation is severe enough to protect the well - being of the son and prevent the spread of racist ideology.
Legal actions could be considered in some cases, especially if the teachings lead to the son engaging in discriminatory behavior that violates anti - discrimination laws. At the same time, positive role models in the community can be promoted. These role models can be from different races and backgrounds, showing the son that there is a better way to interact with people than through a racist lens.
