But forgetting the morals for a second, doesn't it dilute the message? Here's an amoral analogy: We're running a marathon and I'm currently winning but you're catching up. I'm confident that I'm winning because I take 10000mg of vitamin C every day. But also I'm going to pour burning asphalt on the road behind me. When you lose the race, are you going to reconsider not eating vitamin C every day, or will you blame me for pouring burning asphalt on the road?
