That is not true. There can be complaints to Federal and State agencies by applicants, and civil lawsuits possible. It is your responsibility to justify when a complaint is filed, and businesses are licensed and there are courts of law and regulatory agencies. Also, most business owners want the best qualified employees regardless of their race, age, gender, etc. And, many businesses cater to a multi-cultural community and any hint of discrimination drives customers away.
The known continued existence of discrimination in some places inspires government agencies to make preference programs in their hiring favoring non-whites. Tough to complain when you are adding to a problem.
