I don't think it's a mom who wrote it.
What mom thinks and writes like that?
It sounds more like the mindset of a 12-year-old boy.
I mean what adult deals with a problem child by writing an anonymous letter?
What adult evaluates a child according to whether he will marry or have a job?
What adult writes sentences full of exclamation marks?
Everything about this situation suggests that it's some kid.
Not to say it isn't awful to receive such a letter.
But I suspect we're making a bigger deal out of this than it really is.
Adolescent boys have thought like this for ages.
They will continue to think like this. Many adolescent boys are just a**holes. They think they're cool by putting down the "retards" because that supposedly builds them up.
Although I do think that there is plenty of dehumanization of the disabled, I don't think the immature mind of a teen boy really reflects the opinion of the average adult.
I think there is a kid out there who got fed up hearing the autistic boy's noises, didn't know how to stop it and wrote this mean letter.
It's nothing more sinister than that.
