I don't think you can hold a newscaster's past against them, at least not out right. Every journalist probably has personal feelings regarding SOMETHING they covered. The key to good journalism isn't that journalists are bias free, its they they parrot (all) the facts without introducing their bias.
Give to every other human being every right that you claim for yourself that is my doctrine. He that would make his own liberty secure must guard even his enemy from oppression; for if he violates this duty he establishes a precedent that will reach to himself. - Thomas Paine
Even unwanted humans should have rights.
