You edited to add 'nowadays'.
What a cowardly edit.
How was it okay to back the terrorist group ANC (Nelson Mandela was a convicted terrorist) and call for the fall of the Apartheid South African government in the 80's, yet not okay to call for the downfall of the Apartheid ethnostate that Nelson Mandela said the concentration camp they created (Gaza) was worse then any of the Bantustans created by Apartheid South Africa?
What Israel is doing is quantitatively worse then Apartheid South Africa. Why was calling for the end of that government okay?
$5 says you're too much of a coward to answer that question, even if only to yourself.
Probably the only non-evil response.
It fails the 'all it takes for evil to win is for good men to do nothing' test.
It fails the 'If I was in Nazi Germany, I would have resisted' test.
But I suspect that that isn't the reason used by Peter_Arbeitslos@feddit.de
I would guess that he would have supported Rhodesia if his government said that to oppose them was racist against white people.
