The Church has moved somewhat slowly in some areas, but it also has moved quite quickly in others - and when it moves, it tends to move MUCH more quickly than other religions. It's a mixed bag in that regard, but I've seen too many organizations (including religious ones) that have moved too quickly and suffered terribly for it to want the Church to move more quickly on everything.
Of course, there are issues where I wish things could have happened more quickly, but as someone who has studied and implemented organizational change management, I recognize the principle articulated in the Allegory of the Olive Tree in Jacob 5 - that the bad fruit can't be pruned faster than the strength of the root to absorb the trauma.
Something for consideration:
That's true of individuals every bit as much as for organizations. Radical surgery sometimes saves - but sometimes it kills.
