No, I think he's trying to say that all sexual sins are offensive.
By far, I think, most socially destructive sins are done by heterosexuals: contraception, sterilization, abortion, divorce/remarriage.
THis ratio may change as society gets sicker and sicker.
By using the same word to describe them all, he is trying to say that all sexual sins are equally offensive. Based on Catholic Tradition and Scripture we know that this is not true about sodomy. I'm really not sure how anyone can read his words and not see that this is about not offending the homosexuals.
