I've watched a fair amount of Piers Morgan since LKs departure and I have no idea what his political leanings are or whether he has any political agenda. I would guess his agenda is to gain ratings through multiple strategies -- one of which is by being provocative with his guests.
My guess is that Morgan's incorrect terminology, while wrong, probably doesn't change anyone's view of the conflict -- which is most simply described as 2 wealthy parties being unable/unwilling to agree on how to divide millions of dollars. Simplistic, but I think that's how most people view it.
I watch Piers, Nancy Grace, Bill O'Reilly, Chris Matthews, etc. with the expectation that they will grab any opportunity to provoke an emotional response from their guests and their audience. I think I'd be foolish to expect otherwise.
