Noting that Matthew 23:13 shows that Jesus reprimanded the Pharisees for being a stumbling block to people seeking God, this is why I have trouble with Cardinal Dolans open arms stance on homosexuality.
The blind are following the blind.
Christ told us to take His message to all. The Church has two outreach programs - Courage and Encourage are spiritual support groups helping Catholic men, women and their families, to live in accordance with Catholic Church's pastoral teaching on homosexuality.
There is no difference in the eyes of God with the sin of adultery or the sin of homosexuality, both punished with death in the OT. We should try to help our failed brothers and sisters to "Go and sin no more" regardless of their sin.
We are all sinners.
