The Church does not need priests who practice sodomy, just as she does not need priests who practice fornication and adultery. The Church does not need priests who experience deep-seated lust for men, just as she does not need priests who are constantly lusting after women. The Church does not need priests who buy into the gay lifestyle, just as she does not need priests to buy into a playboy lifestyle. 

I think that is pretty much what is meant by "practice homosexuality, present deep-seated homosexual tendencies or support the so-called ‘gay culture.’”
