I don't know. Sometimes I feel the gays can be very hyper-sensitive. Some things really don't offend me as much. I don't think there is anything wrong with her saying that she doesn't want her son to be gay, because as a gay man, watching my brother grow up, I never wanted him to be in the lifestyle either.
But the part about beating it out of her son if he was gay, was a bit much and that maybe where the sensitivity comes from.
