The basis of the Reformation rests largely on first millennium heresies among which Paulianity is prominent. The Reformation was a repudiation of Christianity and that meant that they left no heretical stones unturned in the development of their various doctrines. Which, of course, immediately diverged in all directions, as individual men discovered that suddenly all stops were out; there was no Church and you could come up with whatever beliefs that you wanted, with no limit on the imagination.
The antiCatholics here are simply following in their own sacred tradition of antiCatholicism. Look at the incessant antiCatholicism of the 1800s in the US, Canada and the UK for evidence of that.
The anti-Catholics here aren't your garden variety, sane Protestants. They are fringe creatures at best that in no way represent the decent and pious people of Lutheranism, Anglicism, Baptists, Methodists and Episcopalians who differ from Catholicism in doctrine but are not disageeable. My guess is that if you were able to check their attics you would find pillow cases with eye-holes cut in the corners.....
