[Seth Godin:](http://sethgodin.typepad.com/seths_blog/2006/08/marketing_moral.html)
> I have no standing to sit here and tell you that it’s wrong for you to market cigarettes or SUVs, vodka or other habit-forming drugs. What we do need to realize, though, is that it’s our choice and our responsibility. As marketers, we have the power to change things, and the way we use that power is our responsibility–not the market’s, not our boss’s. Ours.
If you don’t get why this is important, you need to realize that the task of Christian evangelism is essentially a task of marketing.
