Do Businesses Have the Right to Refuse Service Based on Moral/Religious Objections?

[Soon]

I just came up with this idea for a poll based on this article out of New Brunswick:

Florist refuses to outfit same-sex couple's wedding

Apparently, there are still a number of people who feel that this florist's religious beliefs should take precedence over the customer's request for service. Maybe some of you agree that the florist has every right to refuse service to a same sex couple in that it is contrary to her personal beliefs. If so, I'd like to hear why.

There are many in our Canadian community (readers' comments under the CBC article) who DO believe that it is, and should be, an acceptable choice for this private business owner to refuse florist service for a marriage in which she has grave moral objections. Some are citing our freedom of religion clause...others have cited the same document (our Charter as well as NB's human rights' code) in support of the couple and their request for service.

Despite the laws (regarding LGBT protection/equality) where you currently reside, do you believe it is acceptable to refuse service to a customer based on their sexual orientation/gender identity due to a business owner's religious or personal beliefs and objections?

This may be a ridiculous question to be asked of our community, but I was curious if others in our community DO think a business owner's religious/moral beliefs should an acceptable reason to deny a consumer's right to request/purchase a service.
