I also don't give a single shit if you've "been hostile to me." If you are deflecting away from modern day injustices being directed against a minority population with "But...but remember this one time in history...!" Then you're just as disgusting as cwolff.
It really is simple. Say what the South African government is doing is disgusting.
Here is me being a normal human who is capable of being consistent: I thought the South African government during apartheid was wrong and I think the South African government of today is wrong.
Look at that! Consistency. Let's see if either one of you can be consistent and call out the modern day South African government too.
