Is homosexuality an important religious issue?

[QueenBee]

I feel people of faith, as well as others are making this a bigger issue than it actually is. For God's sake. I always argue that if this is what people consider the biggest issue in the world, than I am ashamed to be a resident of this world.
Arizona may be having a new law that allows business owners to deny service to gays based on religious beliefs.
How does any of this differ from 50-60 years ago when blacks could not come into a business? I would wager a bet that these same business owners would never deny service to a black because "that would be wrong".
Homosexuality is no more a choice than heterosexuality. Did any of the straight people here wake up one morning and said I CHOOSE to be straight. Or did you just always know you were?
