While I don’t know about the profit part of what @poche said, I can attest at the outright hatred a number of protestant ministers have against the Catholic Church. For most of my life, I lived in Spartanburg, South Carolina. For about the first seven years that I lived here, Catholics were outright hated by many of the protestants in town.
The protestant preachers in the area would say anything about Catholics: that we sacrifice infants at the Easter Vigil, we sacrifice chickens to the various Saints, we add marijuana to the incense bowl to make everyone believe what we teach, molesting boys were part of priests official duties… etc.
I have had friends’ cars broken into and defaced because they had rosary beads hanging from the rear view mirror. Our Parish had been broken into and someone tried to pry open the tabernacle in an attempt to desecrate the Eucharist. Cars have been keyed in our parking lot during Mass. Another time feces was thrown at our large nativity scene by the side of the road. Thankfully, it has gotten a lot better in the past decade and a half and now the police actually investigate crimes against the two Catholic Churches in the area.
The main problem was the head pastor of the main Southern Baptist church in town. He preached his hatred against Catholics from the pulpit and many of the other protestant ministers (even in other denominations like Presbyterianism and Episcopalianism) followed his lead. Eventually, the Baptist minister was replaced and the new minister worked hard to change the tone of Protestantism here in Spartanburg.
I once met an African American auxiliary bishop who told me that he understood the attitude toward Catholics in South Carolina. When he had been a boy, their parish in Missouri (I think, it has been a while) was going to send a group to South Carolina to attend a Civil Rights rally. When the diocese heard about it, they stepped in to stop the trip. It wasn’t that they were African Americans attending a Civil Rights rally that had the diocese scared for those attending. It was the fact that they were in more danger being Catholic in South Carolina at the time than they were, being black. They wouldn’t just be in danger from the white segregationists but also from the other black civil rights marchers simply because they were Catholic.
