My experience suggests the contrary (full disclosure, I'm Catholic, although I don't go to church regularly). Your argument is against religious INSTITUTIONS, which are, like all system we create, flawed. Religion itself is separate from what people do in the name of religion, just like the things the US has done in the "war on terror" is separate from the idea that terrorism is bad. Yes there have been bad decisions, but over thousands of years, for many of which the governments of the time did horrible things, it is not that surprising.

The reason many Catholics started coming to services again under the new Pope is not that they suddenly believed in God again, but that they feel the church has shifted to a stance they can support.(although it still has a ways to go IMO)
