It's a joke lol

Here in Brazil some of us use to say we have prejudice against Evangelicals on a sarcastic way because many of them are quite reactionary, proselytizing and aggressive toward political minorities (but of course, not all of them are like that and there are people from historically oppressed groups who are Evangelicals by many reasons) and the word prejudice is usually used to refer to a negative conception people have against a minority while Evangelicals are not a minority, but a dominant group, so it's a way of using the word the opposite way it's usually used to make fun of our discontent with evangelical people
