The problem is that without anti-discrimination laws, bigotry might lose on the collective level, but it won't lose on the individual level. The purpose of such laws is to grant a remedy to individuals who are harmed by discrimination.
To be clear, I oppose most federal antidiscrimination laws, because most of them are unconstitutional. However, state legislatures and state courts should definitely grant a remedy to individuals harmed by arbitrary discrimination.
