Soory carole,
If you are business you have to make allowances for your beliefs.
If you are Christian there are more things than gays to worry about,what about unmarried heterosexual couples,or what about a Moslem guest.
I know of a veggie who runs a B&B,she has had to come to terms with cooking bacon,sausages etc for the breakfast.As she say "I don't eat the meat,I only cook it"
Of course if she felt strictly about being a veggie she might not be able to run a B&B.
This couple are really hypocrites,they want the money from their B&B, but don't want it if it comes from persons who violate their beliefs.Well, then they shouldnt be running a B&B.What would they be like if they ran a shop?They would often be serving gays,but would not be able to tell they were.
Basically they dseserve to go out of buisness.We all have dislikes that we could use as an excuse(in many areas of life) we either put the dislike first,or we manage to be pragmatic and steer around it.
This couple want guests,but only when it suits them,and they were prosecuted for illegal discrimination NOT for being Christian!
