I'm of the opinion I don't want anyone banning something for my own good.
We've seen to often how that leads to basic rights being taken away.
We've also seen that once something is banned? A simple change in it's chemical make up bypasses the bans. With a usual bad out come. (Bath Salts come to mind)
If you are going to protect me by banning Trans fats?
I'd expect you'd want to protect me by makeing me wear a helmet when I ride my Triumph.
How about a ban on obese people eating junk food?
Say scales at all Fast food joints and if you get pinged you can't eat there?
