No one is saying that people with same-sex attraction don’t have genuine feelings and real lives. Strong feelings, however, do not equate appropriate behavior if one acts upon those feelings.
I can have strong feelings towards a married man, but it would be wrong of me to act on those feelings.
I can have strong feelings towards a person who deeply hurt me, but it would be wrong for me to hurt them back.
Our feelings are definitely a part of our nature, but they do not define us, nor should we act upon all of our feelings, even if they are strong.
People are afraid of saying that our strong feelings, yes, even feelings of attraction and emotional connection, can be disordered. There are mothers who have strong emotional feelings for their sons, and they pamper, baby, and coddle them, but this is not healthy for mother or son, especially when the son reaches a certain age. The mother may be having extreme motherly affection for her son, but taken overboard, this is disordered.
A person with a personality or certain attachment disorders has often intense feelings of attraction, but that doesn’t mean those attractions are healthy.
We also ALL have lives… even hardened criminals have personal lives where they have suffered pain from others and in relationships. None of this constitutes condoning homosexual behavior, which is highly disordered.
Your song has no “argument” to it. No point is made as to why same-sex attraction is good. I have no doubt that she is experiencing a longing. Longing, attraction, emotions, etc. are not the same as love. One can love without any of these “feelings”, just as one can experience all these feelings without love.
