A good article in JWire by Michelle Coleman, who joined a BDS Protest "Undercover".
Quite short and an amusing read. It is quite funny to hear about a South African being lectured about "Apartheid Israel" by people who don't even know what Apartheid means!
In South Africa, Blacks and Whites had separate buses and seats. In Israel you'll end up mixing with Muslims, Jews, Christians, Africans and Thai.
