Hmm...I would have told the host, “No phone sex for me. I’ll meet you for an interview & record it on my iPhone. Otherwise, pack sand.”
An audio recording can be cut & spliced & make you say crazy stuff. Remember Lying Katie Couric, and that’s recent.
Real question: did you have any doubt where this host stood on the subject of gun rights?
No.
I did contact a close friend, Alan Korwin, who has done numerous interviews on the subject.
It turned out that they had contacted him as well.
He advised me to accept the interview. He said that the interview might inform the producer to some extent, and do some good. He also assured me that we both were too informed and careful to be included in the show.
He was exactly correct.
