Gotcha. OK, so, you are fine with cake bakers refusing homosexuals, business refusing service based on skin color or any other reason? Making up their own zoning and inspection rules, if they choose to have any? Right? Their property, their rules, yes?
See, your home is not a place of business. You're not asking to be able to do business. It's private and personal. A business is seeking to conduct business within a community and that community has the right to impose rules and restrictions be it zoning, licensing, inspections, accommodations and so forth including civil standards such as not being able to discriminate. If you choose to conceal carry, TARGET is imposing you not only violations on your second amendment rights but, adding to it stigmatizing you and inconveniencing you as you may like to be out and about and the wife asks you to swing by TARGET to get some stuff when you had not planned to go and had accordingly brought your weapon along. Or whatever reason.
Maybe you're one of those folks that likes to think of corporations as people and as having the same rights as citizens? Or, maybe you think a business is a different thing than a citizen?
To me, there is a world of difference between the two. This is not esoteric stuff.
To your first point, yes. I believe in voluntary transaction. Anyone should be able choose to do or not to do business with anyone else. Now, whether choosing not to is a wise business decision or not is up for debate. Personally, I go for longevity and sustainability in my business dealings. But if a baker doesn't want a bake a gay cake, the government should have no say in forcing them to do so. Same with blacks, Jews, etc.
Reading ahead, I think you and maybe some others (nutz) are conflating a couple of different concepts.
- public vs. private property
- public accommodation
Unless owned by government, a retail outlet like Target is private property. I have never head of a retail outlet being owned by government (maybe a gift shop or book store at a public art museum perhaps), but certainly Target is not owned by any government. There could be examples of a Target or Starbuck's, for example, being situated on a military base, selling products to members of the military. That is of course on public property, but there is likely a rental agreement which means that the store itself is conveyed the usual rights of private property owners.
A public accommodation is a place that is open to and used by the public, even though it is private property. This includes hotels, restaurants, and of course, the point of this discussion, retail outlets such as Target. Under the Civil Rights Act of 1964, there are a few limits on the restrictions a public accommodation can put on the people who use a their services. For example:
A PA cannot discriminate on the basis of race, color, religion, national origin. They are, in fact, still allowed to refuse service to anyone based on disruptive behavior or because they don't like the clothes you wear (including guns). I'm sure you know how this work, if an Arab enters your store wearing a garish Hawaiian shirt, you can ask him to leave because of the garish Hawaiian shirt, but not because he is an Arab.
There's also the ADA (Americans with Disabilities Act) which makes it illegal for a PA to kick someone out for disabilities -- in a wheelchair with a colostomy. And I think women who want to breastfeed in a PA might be covered here.
So yes, there is still considerable leeway here. In my view, this falls under the category of a private property owner can ban guns if they want to, but if it is going to severely impact their business, why would they want to. Banning smoking is no different.
Bottom line, this isn't a Second Amendment issue. Not even a little bit.
