ABC presenter Patricia Karvelas was “eaten alive” on air by Lidia Thorpe as the Senator showed why she is “suddenly a big new danger,” according to Sky News host Andrew Bolt.

“Karvelas was shamed into near silence ... as Thorpe promoted her apartheid politics, and confronted Karvelas with the horrible thought that this ABC presenter wasn't as progressive as Thorpe and was trying to foist on poor, innocent, oppressed Aborigines a toothless Voice,” Mr Bolt said.

“In a big finale, Thorpe played not just the race card, but the gender card as well, and Karvelas, poor progressive Karvelas, who'd called Linda Burney a legend, had nothing left to say - not a squeak.”

Mr Bolt said he doubts anyone at the ABC and other media stations who know how to say no to an Aboriginal activist, “even one as dangerous as Lidia Thorpe – no one dares”.
