DETROIT, Mich. -  

A Detroit school teacher was suspended for playing a pro-gay song to her students.

Susan Johnson said one of her students suggested playing a song about bullying and growing up gay.

After learning the song had no profanity, Johnson says she continued playing it as a way to teach students about diversity.

When school leaders heard what happened, Johnson was suspended for three days without pay, even though several faculty members and students rallied behind her.

"She's a wonderful teacher. I think she should have her job. She should be able to come back and continue teaching," faculty member Bridget Kozlowski said.

Johnson was allowed to return to the classroom, but the incident has now gained the attention of the American Civil Liberties Union who is investigating to see if her rights were violated.
