Do you think tough love is sometimes necessary?

I recently watched a comedy special from George Carlin, in this special he absolutely takes a verbal machine gun to obese people, fast food and consumerism.

I understand he would offend many people but it actually helped me pay attention to my own expanding waistline and motivated me to smarten up.

I am alone on this, or can blunt in your face honesty motivate you?

Maybe we need an angry grandpa hurting our feelings again?
