@freemo but I think that a modern drag queen reading books to kids is likely that she is doing some sort of "political action"/propaganda.
If there is a drag-queen who is a normal teacher, with her character and attitude, no problem. This can be also very formative for the kids, because this open their minds.
But if there is a political agenda, and the drag queen teacher go only from class to class for instilling doubts in the children, then I can be suspicious, and I don't like it.
Mrs Doubtfire was not about a teacher instilling gender/sex related doubts in the children, but he/she was a normal/funny person.
