Practising? you originally said "People either lost their faith or walked away from the churches"
Most studies suggest that the number of Catholics has actually only reduced by a low percentage. Studies also suggest that the most common reason for people turning away from Christian faith is due...
Do you have some evidence of this?
Most research I've read suggest that the large increase in people switching from Christian to non believers is not related to scandals or crimes, but actually due to science.
