"Thing is, people think this is "a British interview"

Well it is...as you acknowledge below:

"In any sane country..."

We've seen the same formula played in every interview by Piers Morgan:
Every guest must accept the establishment line that the central issue is the demonic Hamas: not the Palestinian people or the murderous Israeli state.

Once you have that settled the guest is "in the bag" so to speak...and any other point he has to make is mere " special pleading".
