I posted this over at Kos' sister site Street Prophets. I can definitely tell you that the right wing does not have a monopoly on this type of 'communication'. But they certainly seem better at it!
--- more under the fold ---
The following is a short list that sticks out in my mind.
Domino Theory = Rise of Communism
Moral Majority = Religious Right
Trickle Down Economics = Tax cuts for the upper 1%
Service Economy = It's ok to be poor and barely make ends meet working 2 or more jobs
Tax Reform! = Raising taxes!
Stay the Course = Failed Iraq Policy
Healthy Forests = Clear cutting forests
Ethnic Cleansing= Genocide
Ethnic Purity = Organized Racism
ok ... to name a few
I am hoping for others to contribute to this diary with some of their own!
