Science says homosexuality is right because of a “natural” desire. Legality and rights are not based upon desires. Just because we have a desire does not mean we have a right to carry out that desire (Romans 6, Gal 5, Eph 5). If an adult man solicits sex with an elementary girl because he has a desire, nobody is saying “let him do it; that’s just the way he is”. If a man makes a sexual comment or commits adultery, we don’t just shrug it off saying they are just like that; they have those desires. Desires are immoral not inevitable.
