Every business that has tried this and gone to court over it have lost, every Christian business has lost in court and most have lost their business after the bad press and attorney fees.
But for Heaven's sake, don't just give in!
At some point, enough patriots are going to rally that, when the gaystapo comes for your business, they're going to have to shoot their way in. At that point, the fags that started the shyte are going to understand what it means to awaken a sleeping giant.
"To every man upon this earth
Death cometh soon or late.
And how can man die better
Than facing fearful odds,
For the ashes of his fathers,
And the temples of his gods ..."
-- Horatius at the Bridge, from the Lays of Ancient Rome by Thomas Macaulay
