The Constitution forms the supreme law of South Africa. It is a secular law which stands to prevent the persecution of people on the basis of race, ethnicity, language, gender, sexual orientation - and also religious freedom.
Of course, most of the time you need to belong to a minority group of some kind to confirm that the law and the letter are being carried out in real life as they are on paper. In South Africa I can attest to the fact that the gap between the paper law and the real life application of these laws - which once seemed to be narrowing, is now just as wide - if not wider than ever.
