Then please use God's Word to support your claims. If not, you are making just an assertion.
The reason so many Catholic apologists are former Protestants is simple. Most were very familiar with scripture and through many hours, days and sometimes years they wanted the fullness of the Christian faith and could not continue living a lie. They became Catholic. They are also hated with a passion by some Protestants who can’t get it through their thick skulls that someone would actually become Catholic. It’s kind of funny and sad for the same reasons.

Tim Staples’ conversion story from Assemblies of God youth minister to Catholic is fascinating! I learn so much about how others view the Catholic faith from converts and admire their love for Jesus. There are still so many misconceptions that Protestants and non-believers have. Staples’ is now head apologist at Catholic Answers. He must have a nearly photographic memory; I am always so impressed at his recall of book, chapter and verse when he responds to callers on the Catholic Answers radio show, Catholic Answers Live (on daily from 6:00 to 7:00 ET).
As with many who have converted, Staples’ had a deep knowledge of scripture, but the AoG has the doctrine of “bible alone” or “sola scriptura”, which ignores most of sacred tradition. I have a deeper appreciation for my Catholic faith after knowing the struggles and challenges Mr. Staples went through. I have seen him in person; his enthusiasm is contagious. He is a wonderful preacher and presenter.
