I don't think the issue has ever been hatred of homosexuals, but rather the twisting of God's instructions to us.
Woe to those who call evil good and good evil, who put darkness for light and light for darkness, who put bitter for sweet and sweet for bitter!
Woe to those who are wise in their own eyes, and shrewd in their own sight!
Woe to those who are heroes at drinking wine, and valiant men in mixing strong drink, who acquit the guilty for a bribe, and deprive the innocent of his right! (Isaiah 5:20-23)
When someone calls homosexual conduct a good, or, as one poster would have it, a 'not-evil,' then we are abandoning what the Scriptures and centuries of the Church's experience has taught us. We are foresaking the gift of sanity for the realm of self-indulgence of the fallen intellect and flesh.
I have no doubt that there are many homosexuals who are worthy of the Kingdom, and far more of them deserve a place at the Lord's Table than I do. But, the price of admission is repentance. If they do not repent of their proclivities, as we all must do with our temptations, then they cannot enter the Kingdom. We are called to enter, but we must have the robe washed by Baptism and many tears. Just because the Lord has opened the feast to us sinners, we ought not hop the fence. We must still enter the proper way... through the Door of Repentence.
Excusing homosexual conduct is akin to denying them their means of salvation: their struggle with this temptation will save them, yet we seek instead to deny this cross. It is never a loving act to tell another person to give in to their temptations. It is even worse when someone tries to misrepresent the Church's teachings on the matter.
This is what most of us are reacting to.
