Why do the parents of severely handicapped kids send them to school?

Because the school has to provide "equal" education for every child, even the ones with the approximate brainpower of spinach.

At the taxpayers' expense, they have to provide someone to feed the little retard, wipe the little retard's ass and play fucking games with the little retard all day, and call it education.

It boils down to this: You don't want to watch twitchy-drooly the short-bus special eat lunch, neither do it's parents.

They're so sick of their little "present," school becomes "send it there to keep it busy so we don't have to pay for invalid care until it turns 18."
