Being a lay person, I've not really discussed the differences with a priest. I do know that the Catholic church lays out rules for mass that must be abided. What I've read is that it has to do with a Pentecostal movement. Pentecost was when the Holy Spirit descended on the Apostles and they "spoke in tongues". (Think Quakers and Shakers.) Pentecostalism is traditionally Protestant Christianity. Some Catholics are trying to bring Pentecostalism into the Catholic church. Traditional priests feel this is a movement away from Catholicism, from what I understand.
>> I’ve never seen a white Baptist church where the congregation vocalized out of turn freely.<<
I'm sure Baptist churches range in the way services are held. Let me clarify that - Southern Baptist. Once, a friend of ours was visiting and he was Catholic. He brought his girlfriend to our mass. During the mass she threw out a few "amens" during the Homily, or when the priest speaks along with a few "thank you Jesus!". It really carried in the otherwise quiet church - it echoed. All eyes were on us, needless to say. They were white and he later explained she's Baptist.

As I understand it, Pentecostals leave their denomination so what you are describing sounds more like Charismatic - people who believe in speaking in tongues as the first manifestation of the holy spirit but they stay in their denominations.
