So far the "politics" are 3 to 2 Liberal:
3: Karen Hayes and Wayne's sister (bleeding hearts crying about Muslim civil liberties), and gullible family protecting Muslim neighbor
2: Racist neighbor going after Ahmed; Curtis trying to kill Fayed (with good reason)
I don't think the show is liberal at all. I think the program is giving a conservative argument on appeasement being a danger to the country. It would be liberal if they showed how appeasing terrorist's demands helped, but its not the case here.
