Ultimately, the trivialisation, commercialisation and exploitation of sex are really just sex removed from its meaning. Homosexual behaviour runs counter to the meaning of sexuality because sexual differentiation enters into the very meaning and purpose of sexuality. This is not a judgement on the intentions of homosexual persons, but on the meaning of their actions. It is sometimes claimed that homosexual behaviour is not wrong because it follows the natural inclination of homosexual persons. Inclinations, whether of a heterosexual or homosexual kind, are not themselves sinful.
Sin involves a choice or decision that one freely makes.
Inclinations, on the other hand, precede our decisions. The claim that homosexual persons cannot help their behaviour, that they have no other choice, is demeaning. Apart from cases of truly compulsive behaviour, everyone is responsible for their actions even if they are not responsible for the inclinations that precede them. To experience an attraction to others of one s own gender is a phase of development for some people. This does not prevent their heterosexual development through appropriate socialisation, and through the avoidance of homosexual activities that reinforce the homosexual inclination.
