I'm raping the fuck out of him when I ask for wheat bread
You'd better check with the Interstate commerce people, that wheat bread thing again. Oh never mind, that was PRO
Logically, I can see the point you're making and even how you arrived there. I think the problem with the analogy is the tenuous correlation between "a person comes to your house and rapes you" and "a person enters your store to buy goods that you presented as for sale to the public".
Example:
An American Indian walks into your doughnut shop. There is a box of day old doughnuts on a table near the door. Being an angry descendant of General Custer, you refuse to sell him the box of doughnuts. He places more than enough money to cover the posted price plus any sales tax, grabs the box and exits. Who was harmed and exactly how were they harmed? You received the full payment you were offering the goods for and sold goods that were soon to go from an asset to an expense.
The only harm I can see is mental. You weren't allowed to express your prejudice and it pisses you off. Not you personally, but you as in the store owner in this example.
As a current small business owner and seasoned salesman, the only color I see in my customers is green.
I think the issue has been presented as a racist thing, when I view it as a property right thing.
Please keep in mind I am not advocating people discriminate based on something as silly as a racial difference. I am advocating that a property owner, if he remains on his property should decide with whom he will interact with, trade with etc. If another person makes that decision for the owner, hasn't the owner suffered some kind of loss to his property right?
So if a person, say an 8 year old uncle buck, only wants to invite kids with habitrails to his birthday party and some ninja turtle playing / no gerbil owning kid shows up, I think it is 'lil Buck's perogative to tell him to hit the road and take his ninja turtles with him.
The whole issue is about force. If a person doesn't own something, the only way you can acquire it legitimately is thru an agreement, not thru the application of force, then it becomes a kind of theft.
