Stop passing the blame to everyone else but yourself would be a good start. Take responsibility of teaching your kids the real values rather than handing it off to someone else.
If you don't like a channel, change it. Not so hard. Most televisions come with parental controls these days; use them. All media, whether portrayed or perceived as neutral, has an agenda, no exceptions. Some try to shove it down our throats or minds more aggressively than others by warping it in palatable wrappers. It is our own responsibility to filter it out rather than blaming them for putting it out in the first place.
