Social justice, as it is popularly used, is probably the worst threat to freedom of religion in America today. Under the guise of helping the oppressed and uplifting victims of society, progressives, using the rhetoric of social justice as a battering ram, are attacking freedom of religion in America. Social justice is not a coherent concept so much as it is yet another form of social engineering in disguise. (See Michael Novak here and here.)
Instead of addressing the real moral problems of society or working to find solutions to situations involving fundamental injustice, social justice focuses on the popular causes of special interest groups. Often, those who disagree with the social justice agenda are accused of injustice, and their right to freedom of religion is trampled over by social justice advocates demanding the rights of special interest groups.
