NO, we can never accept this, but we do accept people. God never changes, His word never changes, and that means that redemption through Christ never changes, it is available to all, even the homosexual!
It is no different for those who have homosexual urges....they entertained the desires long before they acted...then tasted...and now they know that there's a price to pay for doing so...you have to battle what you know that before you didn't know because you refrained.
Same for adultery and every other sexual perversion.....and vice you allow in your life....once you've fallen to it you're bound for resisting it the rest of your life.
