why do you care what tv channel I am watching?
I will assume you are serious.
I believe it is important to support conservative ideals. Watching a channel gives them ratings. ratings gives them sponsors. Sponsors enrich the people who own the channel. Currently, because of a hand off to a younger generation in the murdoch family, there is a wide liberal swing at Fox News and conservatives who want to have an impact will fight that change by going elsewhere and not supporting the sponsors.
This is the way the world works. Your actions can defat your own beliefs if you don’t pay attention.
