"Methinks the lady doth protest too much."
This phrase has become very useful in our current political environment. It's a line from one of those Shakespeare plays where everyone dies in the end, and its use has become a way of pointing out when someone's frantic resistance to something reveals a lot more about their true agendas than they intended to let on. When you know that your government is lying to you and the media is helping them, such things can often be a useful way of figuring out exactly what's going on.
Take for example the way corporate media, proven by WikiLeaks to be pervasively controlled by the Clintons and their allies far more than we ever knew, has continued to run smear pieces on Green Party presidential candidate Jill Stein, even while they assure everyone that Hillary has an insurmountable lead over Donald Trump.
