Who banned it?
Here is the explanation from a SHTFplan.com article:
When Vaus contacted various local and national media outlets in an attempt to air his song as a way to counter the Hollywood and Washington media blitz targeting gun owners, he was denied.
We reached out to Mr. Vaus about his experience and he confirmed the reports.
“Clear Channel refused to allow me to buy time on all of their DC area stations,” said a frustrated but undeterred Vaus.
“On the TV side, the video version has been refused by the two major cable TV carriers in DC – Comcast and ViaMedia. Finally I have attempted to buy time on MSNBC nationally and they have been unresponsive.”
I think ‘banned’ is a bit hyperbolic.
