You have already given an example of the first one being questionable. Lets go through the others:
Human Dignity - the ANC, political parties and the media will outlandishly go ape$hit over an event like PurpleFace, making that person a target for ridicule on the street. Even this case is starting to push everything. You even have judges allowing cameras into court rooms to make a trial into a TV drama.
Life- the same human right keeping terminally ill people from ending their life. Charming. Also the same right that states that the life of a criminal is worth more than your entire net worth.
Freedom and Security of the Person- EFF leader spews hate about arbitrary deprivation of property. Nothing happens.
Arrested, Detained and Accused Persons- /Looks at state of Pollsmoor prison.
Human rights in this country were a noble goal, but idealism isn't the best way to solve the real world problems we have in this country.
