If parents were "aware" and "cared", they wouldn't let anyone with an abnormal sexual desire anywhere near their children.....ever. When a teacher decided to announce that he/she were gay, then parents would pressure the school to remove the teacher from having contact with children, or every parent would remove their children from the school.
A person with a mental disorder that makes them attracted to the same sex has no right to be around children. Actually, no person has the right to be around children that are not theirs. Its a priveledge.
