Just for a little balance here, my church has about 3,000 members.
Over half of them are converted Catholics.
Definitely. The 20 c has seen a shift from ethno-cultural Catholicism of the Spanish, Poles and Italians to religion as a matter of choice. This cause a significant outflow form the Church in favor of the easier theologies of Protestantism, especially in traditionally Protestant America.
So, can your 3,000 ex-Catholics articulate their thoughts on church authority and tradition?
