Don't you understand that according to Holy Scripture and thousands of years of Tradition, homosexual behaviour is gravely sinful? It is through this very behaviour that that homosexuals estrange themselves from the Church.
The Catholic Church has bent over backwards to reach out to homosexuals in the hope that they will repent of their behaviour in the same way as it does to all sinners. It has to stop short, however, and always will in not condoning the sin, whatever the sin maybe.    
The bottom line is that one cannot be a practising homosexual and a practising Catholic.
