According to Boston Globe TV critic Ed Siegel, who thinks folks should chill on the whole Fox-News-is-propaganda and just appreciate it the outlet for what it is--fun.
Note that Seigel doesn't disagree that FNC is pretty much an appendage to the RNC or that it, and especially Bill O'Reilly, spreads misinformation at will. It's just that he doesn't think it matters that much; that people should see Fox News for what it is, “pretty entertaining.”
