The Church itself was not facilitating same-sex adoptions, but as Jacoby (and I) pointed out, they were referring same-sex couples to other agencies.
Jacoby's "no effort to block" is referring to the fact that Catholic Charities did not try to take down the legislation that prevented the 'discrimination' against same-sex adoption, but rather sought the religious exemption for themselves. They simply wanted to run their ministry in accordance with Catholic doctrine--but that wasn't possible with Massachusetts legislation.
Typical of the turd burglar's agenda, they have no tolerance for anyone who will not submit to their every demand.
