File this under Further Proof the Israel-Haters Are Among the Shittiest People on the Planet:Pro-Palestine activists in South Africa are threatening to disrupt international superstar Justin Bieber’s scheduled “Justice World Tour” concerts in Cape Town and Joburg – if the “Sorry” hitmaker does not cancel his upcoming Israel trip. The youthful artist has previously performed in Israel twice. However, #Africa4Palestine activists in South Africa have drawn a line in the sand, threatening to cause mayhem if the musical icon makes it to Israel. —Magama said Bieber would face “serious backlash” if he did not cancel the tour of Israel. “We call on Justin to do the right thing and cancel his performance in Israel or face a serious backlash because South Africans and many across the world will not accept a “Justice” tour which includes Apartheid Israel,” said Magama.
