By "the Church" you mean "the Congregation for the Doctrine of the Faith" which introduced the thesis of "objectively disordered" in 1986, in the significantly titled document "homosexualitatis problema". And the reference of that phrase is to the orientation itself not to sexual acts. That the CDF, like yourself, thinks of the orientation as an orientation to sexual acts and not as a vocation of love is the real "problema", thought up by men who are struggling with their own same-sex attraction. However, following Fr Martin's advice to dialogue only with those who offer a real ground for mutual understanding, I suggest we drop this discussion.
