“What exactly is wrong with being a birther?”
“What’s to be embarrassed about saying so.”
Nothing, other than creating a false association with a fabricated environment of fringe, fear and extremism to shape public opinion, i.e. propaganda.
It’s simply primitive name calling:
Racist!
Homophobe!
Xenophobe!
Nativist!
Right Wing Extremist!
Birther!
“So?”
