That is a silly question. The Catholics almost always write calmly and with reason.
Some Protestants write thus also but many write as if they are snarling and pounding their fists upon the table. Catholics here
almost never accuse others of conspiracy and Evil. Many Protestants do just that. If one is attracted to unreasoning fanatics
then Catholic reasonableness may, indeed, drive them away.It's not the unreasoning fanatics; it is exactly the Catholic reasonableness.
I read the Bible, it says thus and such. Catholicism "missed it by that much". Some of their traditions are opposite of what the Bible teaches; but they're their traditions, and they're gonna keep 'em.
Catholicism is a Bible based religion; kinda.
The prospect of "making it" to Purgatory after decades of good works and generous donations, being tortured for thousands of years in Purgatory, and hearing that the infallible pope has the keys to this enterprise - that may drive away a few people.
Holy Mother Church can dogmatize an invented doctrine (the Assumption of Mary) based upon texts from 500 AD, but HMC cannot accept justification by faith alone, a doctrine taught throughout the Scriptures.
