The same analogy applies to what we watch on TV. What we watch will directly affect our attitudes. If bad company corrupts good morals then wouldn’t bad viewing do the same thing?
In proverbs it says, “He who walks with wise men will be wise, but the companion of fools will be destroyed” Proverbs 13:20 (NKJV).
Those you watch on TV become the companions of your household. If they are bad company you should kick em out. You can do that with the flip of a switch.
