You seem to believe that love requires unconditional acceptance of sin. It does not, as Jesus demonstrated repeatedly. He required repentence before He would heal.
To require your religion to fit your beliefs is to construct God in your own image.
I do not think we should accept sin. I fully support the school's right to expel this girl and have repeated that several times. I agree with many of you about the cost of homosexual parents to society.
I refer to the tone of these posts. There is a level of anger and pride to some of them that is as distressing as this girl's family situation.
