I'm beginning to think that NBC should mean "Neanderthal Buffoon Circus". While Melissa Harris-Perry did issue an apology for her mockery of the Romney baby, Natasha Leggero let loose with mockery of elderly World War II veterans.
The progressives and liberals are definitely dropping all facades of civility. The NBC affiliates are one of the worst enclaves of these people. Take a gander at the entire first link and you'll see a whole list of NBC individuals who had to be shamed into apologizing for their arrogant gaffes. I suspect that list will keep growing even after Leggero utters her "mea culpas".
