So Corporation of Public Broadcasting is dead because govt funds were cut. What made it entitled to live purely on tax dollars?

It is not a govt agency or property. It was not entitled to govt funding. It couldn't generate any funds on its own after all those years?

The USPS is a govt agency and - unlike most other govt agencies - it generates revenue while it serves EVERYONE in America.

PBS, NPR and the like were only serving liberals, foreigners, homos, and dryfronts.
