"...not just affecting the Catholic Church."

Yes, Pandora17! All churches are hemorrhaging, no matter what they permit, encourage or promote whether regarding LGBT issues, other social issues, reproductive rights, etc. Protestantism has fallen from 65% of the country (50 years ago) to 46% today, a minority status.  Even evangelical churches like the Southern Baptists have slipped. Jews have also slipped in affiliation, though have maintained cultural connections. Catholics are just under the retention rates of Mormons and Jews.
