I absolutely love this show.
Your question has come up on this board before, but the short answer is that the writer and producer of the show is deliberately *not* taking a stand in supporting one point of view over another.
ie. it is deliberately ambiguous to get the viewer to Think.
And for anyone who enjoys this kind of show, and is capable of paying attention to the twists and turns of the plot and their relevance to current events, it works.
The show makes you carefully consider the issues, while being entertaining. Good stuff.
