Toni, it’s exactly the opposite. Most people I know don’t have the slightest interest in their friends sexual activities. We don’t define people by their sexual choices but by their character. That’s how it’s quite possible to really like a homosexual person without agreeing with their private sexual activities. What people do in private is only a very small part of who they are as a person and unless someone is shoving their sexual habits down your throat, half the time you wouldn’t even know what orientation they are.
I know I have been quite surprised to find that long term friends are lesbians. Didnt make any difference to our friendship because I’m not there in bed with them so I dont care.

Well how can you disagree with something you have no interest in? I don't follow. Surely you must have some sort of interest in something in order to disagree with it?

Toni, you are being very disingenuous. I said I had no personal interest in the sex lives of my friends, that doesn’t mean I’m oblivious to the existence of homosexuality.
I have no interest in drug addiction either but I’m aware it exists and I’m not in favour of it.
As I have already said, I don’t measure my friends worth by their sexual activities, which I believe should be private. I value them for their character and behaviour. As any parent can tell you, at times your children do things you don’t agree with, that doesn’t stop you loving them.
People throw around the term” hate speech” when in actual fact most don’t hate those they disagree with. They just have different beliefs. The hatred actually seems to come from the opposite direction.

This matter could reopen the Kim Davis case where she refused to hand out a marriage licence to a gay couple for "religious reasons".

The cake baker is an independent operator but Davis was a government employee who refused to carry out her legal duty and the obligations of her employment.
The next step would be supermaket checkout operators who refuse to scan your pork or shellfish products.

As for my remark about the signs I think some customers would prefer not to waste their time going into a shop and being refused service and possibly publicly humiliated.
If the owner sincerely holds those beliefs, why not display them with pride?
Would he also refuse to bake wedding cakes for those having their second or third hetero weddings - considering divorce is not permitted in certain religions, or cakes for Bar Mitzvahs as well?

The sign is no different from those businesses who display "fish" symbols to infer they are somehow trustworthy Christians but in the end it it's just a marketting ploy to gain advantage over competitors. It guarantees nothing.

He's entitled to his personal bigotry but potential customers are entitled to know what sort of person they are doing business with.
He may even increase his business with like-minded people.

Down at my local 'Bigoted Bakery' store the proprietor, a very nice old German chap, Herr Schicklgruber, has a very extensive 500 questionnaire, checking for undesirable customers, which has to be completed each time before ordering... ANYTHING! Just the other day after I successfully, for the first in 5 years, completed the 'Bigoted Bakery' questionnaire in under 3 hours, I was over the Moon in anticipation of enjoying a delicious (so I am told) Schicklgruber delight. But unfortunately when I tried to order a FRUIT BUM, the shop was very busy at the time, seems a Gestapo convention was in town, I yelled "FRUIT BUM HERE!" can't pronounce my "n"'s properly, sound like "m"'s, that was misunderstood as me being a fruit, with that, the nice Gestapo gentlemen threw me out of the shop. I'll try again tomorrow, but this time I'll play it safe, and order a FINGER BUM!

As a customer, you have every right to decide which businesses you want to support, and which ones you don't. Surely as a business owner you should have the exact same rights, otherwise it is a clear case of bias towards one of the parties.

Freedom for one to do as they choose must surely go both ways.
