No. Just trying to show that there are limits so we can debate where they should be set and whether a business owner should be allowed to set them, or if we need the Federal government involved.
The example you gave isn't a civil rights violation. Let's go through a few examples...
My basement floods and I call a plumber. The plumber comes out and and somehow detects my basement is flooded with carbon monoxide. He refuses to service my house. Civil Rights violation?
That same plumber is called to fix a leaking pipe in another house. The plumber shows up at the house and thinks the owner is gay. He refuses to fix the pipe. Civil Rights violation?
I'm sure in the second example some would say the home owner could just call another plumber, right? But if you've ever had a leaking pipe, broken sump pump and a flooded basement then you know time is crucial. Also, what if it's 3am and he's the only plumber you can get a hold of at the moment? The point is if a bakery can refuse to bake a cake, then where do you draw the line? Allowing a business to say no based on race or sexual orientation opens up a dangerous precedent.
