I just want to add on to your reply to justify why it's correct to call the ANC a socialist party that is causing the cultural and economic collapse of South Africa.

You could look towards their policies inspired by socialist thought a.k.a. "social justice" (BEE and expropriation). These policies are actively harmful to development while also turning off any potential investors, and are deeply rooted in socialist ideology.

You can look towards their roots being funded and directly aided by the Soviets, China, Cuba, and several others. Especially their military (terrorist) and propaganda training which was heavily influenced by Soviet foreign policy.

You can look towards their re-alignment of the country's economic and foreign policy to engage with the 2nd world, while turning off 1st world investors. This has given us strong economic ties with Russia, China, and Iran. While most of these relationships are useless, the Chinese relationship has been especially damaging to the development, maintenance, and sovereignty of our national physical infrastructure.

But the most damning evidence is the insane socialist parties that have spawned out of the fracturing of the ANC such as the MK and EFF parties (both militant socialist parties, formed by ex ANC leaders). While their socialist rhetoric had to be contained while apart of the ANC (so as to not further turn off investors), the ANC's weakening grip has allowed these nutjobs to become serious contenders in the political race. If you were wondering what the "kill the boer" chants were about they were at political rallies held by the EFF (Julius Malema) - part of the EFF's kit is a red beret (I wonder where they got that from?).

Voetsek to any champagne socialist that wants to ruin yet another country because it makes them feel good to support people and ideologies they do not understand.
