If I own a business and don't want to hire people with tattoos or drive a red car, it's absurd the government can tell me, as a private business owner, otherwise.
I agree.
The converse is true also. If I, as a business owner, want to hire ONLY smokers, and allow smoking at my place of business, I should be able to.
I, as a business owner, should be able to allow smoking at my business, by the general public, and if someone doesn't like it they don't have to frequent my business.
Sounds fair to me.
