I really like the content too and Isaac & Sarah seem like pretty nice people so it's definitely surprising to me. Given the scope of her comments it's certainly possible she just bungled the interview, didn't understand why her comments were offensive, became embarrassed and refused to apologize. That's its own problem though it shows a lack of understanding which is pretty concerning for someone writing legislation on teaching, especially legislation impacting how the holocaust is taught.
