It is easy to make up reasons why cigarettes should be banned everywhere. The second hand smoke argument that isn't based in fact, the ability to unconstitutionally remove the rights of business owners. and taxing and taxing the one group all races and creeds can agree to gang up against.
But e-Cigs create a true dilemma. They are not bad for anyone, even in the fake ways we have convinced the public to accept. That is why we must ban them entirely. So we can force our will on others and make them feel bad about their weaknesses to enforce our superiority. We need to do this soon, cause if people don't just conform to our unjust abolishment of e-Cigarettes, they might actually start asking questions about how we've made life so difficult for smokers under similar flimsy pretenses.
