Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances.
Gee, look at that. Not one mention of restricting freedom of speech of anyone with money.
Also, what you're saying is that you are not aware of the existence of ABC, NBC, SeeBS, MSNBC, and CNN as counters to Fox News, not to mention Huffypoo, the Daily Kooks, the various print media on line and the print media still using the corpses of trees, almost all of which promote the leftwing dogma shared by NPR that is so damaging to this nation.
NPR is redundant, as is PBS.
There's a completely free market for opposing and alternative viewpoints out there. There's is no need for an unconstitutional federally funded propaganda network, and the mere fact that it is unconstitutional makes it all the more important that it be eliminated if the nation is to ever regain the protections of the Constitution.
