Yes really. While Apartheid is used as a pejorative today because of the association with South Africa, it is actually a legally defined term with classifications.
In 2007, the UN classified Israel as meeting the Apartheid definition. UN Investigator John Dugard goes further stating that Israel Apartheid is infinitely worse than that in South Africa. UN Special Rapporteur, Richard Falk, also has been direct in citing that as a legally defined category which the State of Israel meets.
