That's just the point. Any sexual attraction to the same sex is wrong. It is unhealthy, abnormal, dysfunctional, perverse and always the result of mental sickness or trauma.
These attractions must be cured for the health of the sufferer and of society. Just like kleptomania must be cured.
Based on what?
"It is unhealthy, abnormal, dysfunctional, perverse and always the result of mental sickness or trauma."
Your opinion, followed by a falsifiable claim. If homosexuality is ALWAYS the result of mental sickness or trauma, then why are there homosexuals who have neither?
"These attractions must be cured for the health of the sufferer and of society."
What if the "sufferer" isn't suffering? Why should it be society's business?
