Public accommodations laws are necessary
No they aren't.
Not really, at least not most of the time.
and Constitutional regulatory measures as authorized by the Commerce Clause
Cool story bro.
regulatory policy whose sole intent is to safeguard the integrity of the local market and all other interrelated markets.
If that's what you believe, then you need to grow up. The intent of most public accommodation laws is to stamp out discrimination. Period.
It is perfectly appropriate for states and local jurisdictions to require business open to the general public to accommodate all members of the community, thus facilitating commerce beneficial to the community as a whole.
Wrong. That you are a sniveling lifelong fry maker is what makes you incapable of even comprehending how wrong you are.
There is no law anywhere that requires all people to accommodate everybody. Not accommodating people is a standard part of every business. I don't accommodate people who can't or don't want to pay the price I am asking them to pay. I don't accommodate people when we don't have the capacity to add yet another person on a busy day. I don't accommodate people who are asking for what I feel are unreasonable requests, or requests that I simply don't feel like accommodating. I also refuse to accommodate people who behave poorly, who create a scene, who are hostile and abusive to my staff, who threaten to sue the business or who attempt to use threats of online reviews to get what they want. Just to name a few standard reasons I don't accommodate people.
Public accommodation laws do not require a business to accommodate everyone. They merely create special classifications that prohibit non-accommodation due to special reasons. That being said, they are largely failures. Discrimination still occurs every single day, it's merely dressed up in other forms of pretext.
Now, the most important thing to say in response is this, so pay attention:
Nothing you said has any relevance, nothing you said actually addresses the subject. Your entire post is a fallacy of irrelevance because all you have done is launch off on a tangent while ignoring the question of whether it is good public policy to create new laws that give special protections to gay people, forcing other people to do business in a way they may not want to do or which may object with their personal beliefs. Nowhere do you address the actual issue of the thread. Your entire post is a tap dancing around the entire subject by waxing poetic about public accommodation laws, generally, in hopes that it will slide down a slippery slope and stick. As such, I will not further debate the merits or lack thereof of public accommodation laws generally.
