What does selling cake have to do with any customer's sex or gender?
This is not an issue for sellers to fixate upon!
Any business which refuses to sell cake to one group and not another, based on some "moral" anxieties or apprehensions, (not even grounded in the Bible), is placing its own private privileges above those of all the customers, (by extension), it should be serving.
In fact, businesses were not created to either maximise private profit or to extend moral judgement into the private lives of citizens, including through the sharp knife of shaming: Businesses were created by charter by a government OF THE CITIZENS, to serve all of them alike, in their shared humanity.
It would be a crime to allow businesses to discriminated against particular groups, on matters completely unrelated to commerce, in matters completely having nothing to do with their business, in matters owned to the privacy of those groups and NOT even to the 'privac'y of those businesses' property or premises! Because money does not inform speech. Free people inform speech. People free of those who forever seek to CONTROL, through money, through speech, through moral shaming, through reference to religious abstractions - of which only THEY supposedly know the Truth, or intentions, or answers - or rules.
Simply, businesses may be chartered to serve the public. If they wish, they may choose not to sell sex toys. If they wish, they may write and speak and lobby against immorality but if they want to force that on any innocent segment of the population THEN CLOSE THEM DOWN.
My right to be about my life is greater than anyone else's right to be about their money.
My right to be about my life is greater than anyone else's right to be about their commerce.
Money and commerce - even interstate and global - ARE SECONDARY CONVENIENCES TO INDEPENDENCE, AS THEY ARE TO FREE SPEECH, AND AS THEY ARE TO FREE ASSEMBLY, SOUL - AND GENDER IDENTITY.
If an individual feels offended that any business should refuse to serve gays based on "religious concerns," it is THAT INDIVIDUAL, and not the business, who has the higher religious right to prevail in the question. Commerce does not control us, we control it - because it is ultimately an EXPRESSION of popular values.
Small businesses should not obsess over this small stuff, and focus on how both parties have conspired with globalised corporate elites to monopolise, to outsource jobs, to outsource trade, to outsource taxes, and to crowd out small business at every turn, both geographically and through the latest effort to de-neutralise the internet. Forever, their aim is to siphon all the business and profits and capital up to a few groups at the top who, as the supply-side 'SUPPLIERS' of the game, call all the shots. If you want to talk "morality," then look at how this country has been raped.
It is not hard to figure this out! Especially if you understand the Bible!
“You are fettered," said Scrooge, trembling. "Tell me why?"
"I wear the chain I forged in life," replied the Ghost. "I made it link by link, and yard by yard; I girded it on of my own free will, and of my own free will I wore it.”
