This. I'm getting so tired of this mentality that we should be told how to live.
It's not being told how to live, it's safeguarding people from their own weakness and susceptibility to social pressure which leads to something addictive and potentially deadly. There is nothing wrong with that.
People in support, they'll come for alcohol and fatty/sugary foods next and you wont have any defence.
Ah yes, the "slippery slope" fallacy. They came for A, next they will come for B, etc, so they should not come for A.
Because they will ban cigarettes, next they will ban custard creams. Not really the same thing.
