Catholics have certainly told Protestants some real boners as well; certainly it would be inaccurate to say, for instance, that Catholics “worship mary” because of wrong statements made by some Catholics.
Find me some churches that officially hold these believes. I’ve never, not a single time, read these beliefs in the statements of faith I’ve read. It’s not a Baptist belief, it’s not a Presbyterian belief, it’s not a Lutheran belief, it’s not a Methodist belief, it’s not been a belief of any of the various evangelical/non-denominational churches I’ve attended. I have never seen these beliefs as characteristic of any Protestant group I’ve seen or heard of
Your accusation is no better than the accusations of Protestants against Catholics saying that because a very small number of individual Catholics might make some claim, it’s thereby something that “Catholics believe.”
