Also, drag shouldn't even really a part of the gender/orientation discussion. It is an art style (like burlesque). Now, because of the elements of drama, raunchiness, sexuality, and cross dressing, it is an art style that people with gender identity or sexual orientation issues are drawn to.
Unless it is intentionally sanitized of the raunchiness and sexuality (cross dressing and drama is fine), it is typically not an appropriate art form for children.
