Mariah Carey [SEP] Controversies
In 2013, human rights activists criticized Carey for performing in a concert for Angola's "father-daughter kleptocracy" and accused her of accepting "dictator cash." In January 2019, Carey controversially performed in Saudi Arabia. In the United Kingdom, Owen Jones of "The Guardian" found her agreement to perform there questionable as "Carey has famously always had a devoted gay fanbase: in Saudi Arabia, homosexuality is punishable by death." Prior to this, Carey was under pressure to cancel this performance not only because of the murder of the journalist Jamal Khashoggi, but also because of the country's imprisonment of feminists. In a statement to the Associated Press, Carey's publicist stated that when “presented with the offer to perform for an international and mixed gender audience in Saudi Arabia, Mariah accepted the opportunity as a positive step towards the dissolution of gender segregation.
