If you’ll read your own source material you’ll find that even the Pew report acknowledges sexual issues as a reason for people leaving.
The main reason for changing denominations is clear, and it isn’t because of people who live like Ted Kennedy.
“If you believed liberals, most Catholics who leave the church would be joining mainline churches, like the Episcopal church. In fact, almost two-thirds of former Catholics who join a Protestant church join an evangelical church. Catholics who become evangelicals and Catholics who join mainline churches are two very distinct groups. We need to take a closer look at why each leaves the church.
Fifty-four percent of both groups say that they just gradually drifted away from Catholicism. Both groups also had almost equal numbers (82 percent evangelicals, 80 percent mainline) saying they joined their new church because they enjoyed the worship service. But compared to those who became mainline Protestants, a higher percentage of those becoming evangelicals said they left because their spiritual needs were not being met (78 percent versus 57 percent) and that they had stopped believing in Catholic teaching (62 percent versus 20 percent). They also cited the church’s teaching on the Bible (55 percent versus 16 percent) more frequently as a reason for leaving. Forty-six percent of these new evangelicals felt the Catholic church did not view the Bible literally enough. Thus, for those leaving to become evangelicals, spiritual sustenance, worship services and the Bible were key. Only 11 percent were unhappy with the church’s teachings on poverty, war, and the death penalty Ñ the same percentage as said they were unhappy with the church’s treatment of women. Contrary to what conservatives say, ex-Catholics are not flocking to the evangelicals because they think the Catholic church is politically too liberal. They are leaving to get spiritual nourishment from worship services and the Bible.”
