Why are the baptist and extreme protestant churches scared of catholicism?

I am not sure if they are scared. But it is clear that these extreme protestants hate the Catholics. This is mainly due to Satan's influence on them. Since the protestants separated from the mystical body of Christ, they have been easly misled by Satan. They are so confused that they continue to splinter into so many disagreeing denominations, about 33,000 denominations today. The extremists, or the fundies, are hard-core anti-Catholic. Many of them are agents of Satan whether they are aware of it or not.
