The "fact" they brought up about South Africa and the AIDS deniers is old. The health minister at the time (Manto Thabalala-Msimang)who proposed that story has not been in that office since 2008. The president at that time, Thabo Mbeki, was forced to resign by his party in 2008. His successor removed her from office and did not support their views on this. The issue is mostly a non-issue now, with people being able to get ARVs in government hospitals.
Please do your research better. It's bad enough that the existing western conception of "Africa" is that everyone is uneducated and misinformed. It's a political decision people in power make to save money, just like the climate-change deniers in the American government.
