Re: Look out
Interesting you mention C.S. Lewis. Hw of course, was a born-again Christian and, like most converts, much more pious than the standard variety. He believed that there was such a thing as universal morality, naturally a Christian morality. Believing in a universal morality is a necessary first step to imposing it on everyone.

The issue is not that vaping is less lethal than smoking -- it is -- but that you don't want people going from non-smoker to vaper, as that's a retrograde step. Selling vapers with cartoon characters on them and in many different flavours is exactly the old-style cigarette advertising, designed to hook children.
