I have no illusions about Rachel's objectivity. However, I also know if I watch her show I won't be lied to.
she can be interesting, but she isn't all about the truth either. (not that she has the ability to be, as a high paid high profile employee of a corporation with an agenda that isn't based in truth or journalism).
sometimes "truth" isn't just about lying or not lying, but what you report and what you don't report, and what truths you emphasize and what truths you hide altogether.
