Linde was born in Harare, Zimbabwe, to Jewish parents, Roseve (Saacks) and Hilyer (Hilly) Samuel Linde, and grew up in Durban, South Africa.[2][3] At the age of 15, he attended a four-month "ulpan" study program at Jerusalem’s Kiryat Moriah with other South African Jewish students, which he said "cemented my love of Israel forever."[4][5] He matriculated in 1977 from Carmel College in Durban, where he was head boy and earned an honors blazer with colors in academics, athletics, rugby and debating. After a one-year program at the Hebrew University of Jerusalem's Rothberg International School, he received a bachelor's degree in Journalism and Media Studies from Rhodes University, where he won a scholarship from the Daily Dispatch. He went on to earn graduate degrees in sociology from the University of Kwazulu-Natal and journalism from the University of California at Berkeley. He wrote his sociology thesis on the emergence of Mohandas Gandhi as a charismatic leader in South Africa (under Professor Fatima Meer),[6] and his journalism thesis on the homeless in Berkeley (under Professors Ben Bagdikian and Bernard Taper).
