Ah, but I do think there is a role in the government banning some things. Where’s the line in what is acceptable, how does it get set, evolve, etc., sure that is a challenge. Cigarettes are bad, kill people, even people I know, my Dad for one. They are filthy, they cost us taxpayers and society billions of dollars. E-cigarettes are not really any better. Yes, I know some people argue differently but in the end, they are filthy, they stink, and they are unhealthy. Okay, government banning things... good that government puts limits or bans some things that might cause people to be hurt or killed. Require seat belts—common sense but yes, law has to require it to protect idiots from themselves, protect society from having to pay the consequences. Rambling here, not time to discuss in detail. Anyway, I do think there is good and bad banning, a time and place for government to step in. The challenge is the reason, the need, the society agreement for it. We don’t like it, we replace our leaders. Like now, Trump is reversing some regulations, removing some bans that turned out unpopular, unnecessary, and poorly thought out. Others he and no one will touch. Things change.
The governments role in regulating anything is set by the constitution. It’s not based on “times change” “the constitution is a living breathing document” “save people from themselves” arguments. That is the entire concept of liberalism.
Conservatives believe in the constitution, limited government power (limited by the constitution), and freedom. Even if it’s freedom to be an idiot.
“E-cigarettes” (which is a clear misnomer) are significantly safer than smoking. They don’t stink, they aren’t filthy, and they don’t cause cancer. You can not like vaping, that is your perogative, but the risk reduction over smoking is significant.
