I realised that news of that type tends to trigger my "on switch" or putting it another way... I get angry at it too and a drink is a marvellous solution to dissolve my anger.
30 years of alcoholic drinking would indicate that when the on switch is engaged, I have monumental difficulty in finding and hitting my off switch again.
However... I know precisely where the off switch is on any TV in the house.
So I push that off switch before TV presses my on switch.
Hope that helps
