It's the self-esteem groupthink nonsense. In the real world, the hot chili business would be a good opportunity to teach the child that she is, in fact, different from other folks. She needs to learn to be careful in ways other folks don't. But this valuable survival lesson is lost to political correctness.
As politically correct groupthink nonsense goes though, it sure is harmless.
I imagine that the chili is at a hot tempature and they cool it down so she will not blister her mouth. She cannot feel pain. Why they dont have one of the lunch ladies cool a bowl down beforehand for her is beyond me.
