Most Americans aren’t familiar with the British journalism. And yes, Shapiro should have been prepared. What has become truly entertaining is how all of American right wing media has been reduced to a flamethrower C rated website. But since that is what they already were on radio and television, it was easily adoptable for them.Shapiro made three fatal errors in this interview.
The first was that he seemed to be totally unaware of how interviews are conducted on political shows on British TV.
The Devil's Advocate style of interview where the interviewer will ask the guest questions which the opposing side would ask, and the guest is then expected to counter that with a reasoned argument is perfectly normal and Shapiro should have been prepared.
Secondly, he then tried the tactic of attempting to turn the question around by asking the interviewer his opinion on the controversial topic they were discussing, something a seasoned British interviewer will bat away with ease by pointing out that it's the guests opinions that are the topic of the interview.
Finally, when he realised he was doing really badly, he tried the tactic of painting the interviewer as a member of the "other side", and because of this the interview was total biased against him and therefore he was within his right to terminate the interview. The problem with using this tactic is Neil is the most right wing interviewer on the BBC, being also the Chairman of the right wing Spectator magazine and is a former editor of the Sunday Times under Rupert Murdoch.
In this interview Shapiro showed that while he might be good at browbeating 20 year old student's, against a seasoned journalist prepared to stand his ground he's a lightweight.
