The Protestants are no better, they are just as deep in heresy as the sodomites. If anything they are more guilty, the heresies of democracy and rationalism could not have risen without the reformation, so they not only have the sin of disobedience to God upon them but allowed the formation of even more sinister causes.
As I mentioned, error has no rights. There is only one true religion, Catholicism, and no other can be tolorated. Pius IX rightfully confirmed in the Syllabus of Errors the only true freedom of religion is to practice the only religion that is true.
