The “sexualised” appearances of men dressed as women have provoked fury.
Drag Queen Story Hour UK will visit almost 70 events in 20 areas across Britain.
Starting later this month, the group will run sessions for three to 11-year-olds.
Sab Samuel, a 27-year-old male children’s author who performs as Aida H Dee in a sequined dress, runs the project.
The classes claim to “teach inclusivity” and encourage attendees to “get fabulous”.
They will begin at Reading Borough Council libraries on July 25 and will involve 3,000 children.
But the proposed classes sparked anger from parents, with some even trying to block-book tickets to stop the shows from going ahead.
They have sent model letters by the Family Education Trust charity, telling councils the sessions are “highly inappropriate given that the images of men dressed as women are highly sexualised”.
The letter, according to The Telegraph, adds: “To try to blind children to one of the most basic facts of human existence can only be described as a form of child abuse.
“Children who experience gender identity issues need careful and sensitive care, not wholesale indoctrination.”
