That can be said of Catholics, Lutherans, etc too.
I don’t know any Catholics who define themselves as being non Catholic and I have never heard a homily with the subject being the evil of Protestants. Catholics just don’t focus on non Catholics. Many Protestants focus on Catholics to the point that if the Church were to disappear they would be at a total loss of what to preach. My wife is a wandering Protestant and has been a congregant of Presbyterian and several “non-denominational” churches. I go with her from time to time. She won’t stay with one that is anti Catholic to the exclusion of just about anything else and has left two for that reason.
