They don't watch FNC. Most never saw it. They are just bigots. They heard that it promoted conservative attitudes (I'm not sure it does particularly) and they beat on it for that.
They are ivory tower elite spoiled and sheltered little children in adult bodies and they panic at the thought someone might take away the image of a "mommy" and "daddy" government. They are incapable of standing in the world alone and the thought they would need to fend for themselves sends them into fits.
Ironically the conservatives wouldn't abandon them. The true liberals more likely would. See below. Today most socialists fraudulently call themselves "liberal" only because they like the sound of that word better than their true posture's label.
True liberalism advocates: individual freedom, weak government, and free markets. Conservatism advocates: moral responsibility, strong government, and protected markets. Socialism advocates: social responsibility, omnipresent government, and controlled markets.
I have for decades studied philosophies, cultures, and social institutions began because of the confusion resulting from my military experience under the shadow of neo-Marxist propaganda disseminated from universities.
