Repercussions. You're afraid of repercussions.
But the violent criminal acts you describe aren't really in the realm of probability. But the scorn the community would hold you and your business, the loss of sales due to your bigotry, the way you would be ostracized, that's what really frightens you.
You claim you would face physical violence, but it's the economic loss that is most frightening.
A prominent sign citing you 'religious' beliefs prevent you from conducting business with any and all American citizens should be absolutely required. Such a posting warns those who believe all men are created equal that here is a public business that fails to live up to that ideal.
The sign should proudly explain the rationalization used by the bigoted business.
It should read: "My Lord and Savior, Jesus Christ preached "Judge not lest ye be judged". Therefore, we reserve the right to refuse service to deviant Homosexuals"

You leftists are the most violent and evil group in human history. You've murdered 200 million peace time civilians in the 20th century alone.

Only a fool fails to grasp that violence is the bedrock of leftism.
You're crazy. What makes you think these examples of violence are condoned, inspired or conducted by political forces?
But, look at the abortion doctor killed at his breakfast table. That was pure politics. Or the 168 Oklahoma City residents blown to smithereens. That was pure politics.
Yinz guys got guns, anger and a void where morality resides. The Right Wing violence has a track record. Left wing violence is concocted by your feeble imagination.
