Coal mining is dangerous work. Waitressing isn't.
But on either count no one is forced to accept any job.
Inhaling the filth of others is dangerous.
You do not have to inhale anything. You can choose not to patronize a business that allows smoking. Why is that such a difficult concept for you?
Inhaling coal dust is dangerous
Workers need to be protected. Go work somewhere else if you are not willing to risk your health is not protection
There's a lot more than coal dust that makes mining dangerous.
And workers have choice just like consumers.
If you work in a coal mine you accept a risk. if you work in a bar that allows smoking you accept that risk.
Freedom is choice.
I tend to agree with more choice not less.
If you live in a circumstance where coal mining is your only option for employment, just to entertain this analogy, then it's your only "choice". Similarly if your circumstance is that some office is your only choice of employment, and that office is removing your right to breathe simple unadulterated air, then your attitude is
restricting that worker's choices -- you're giving him FEWER choices --- not more.
If a room prohibits smoking, what's the downside? That a smoker who wants to pollute his own lungs has to take it outside. If a room doesn't prohibit it, what's the downside? Innocent non-smokers get cancer.
You have the "right" to give yourself cancer. You do NOT have the right to give it to me against my will.
