I had a recent heart-breaking conversation with an ex-Muslim. He continued to go to the local RC church and request baptism. He had read the entire Bible multiple times by that time. The priest put him off at first, delaying him. Then he told him he could not because his bishop had forbade it. And eventually assaulted him verbally in front of some other friends of his (who were Christians) and said that if he came to mass again he would call the police. Ultimately, he told him he was fighting against God who had determined that he be born into a Muslim family.
He will be baptized, but almost certainly not into the Catholic Church, because they have refused him. Now who is at fault for this man not being in communion with 'the vicar of Peter'?
One bright spot: some of the young laity who had witnessed some of these things told the priest that he had not acted correctly.
The branch that does not bear fruit is cut off and thrown into the fire.
