Is racism universally (that is, objectively) wrong, or is this something that people should be free to decide for themselves? In other words, is racism something that you think should be wrong at all times for everyone in all cultures and communities, or is this merely your personal preference?
If there is one thing Christians can wholeheartedly agree with young postmodern secularists, it is that, in large part, they are motivated by altruism, a strong desire to advance human rights, and to care deeply for the universal welfare of humanity. There is a tendency among young postmoderns to want to treat with benevolence all people regardless of their ethnicity. This is truly to be admired.
At the same time, however, without blinking an eye, secularists will openly tell you that there is no objective right or wrong - that all morals should be left to the individual to decide. That there is no cosmic or ethical order outside of subjective preferences. But if morality is nothing more than our expression of personal preference or feelings, and does not exist independent of them, then why do people (even secularists) find universal judgments to be irresistible in practice? Their views of racism is a good example. Even the most ardent materialists are unable to refrain from passing moral judgments, even as their philosophy tells them otherwise. They live as if we are accountable to a moral standard that exists beyond themselves.
