Have we become used to or immune to mass shootings?

Absolutely, and maybe that's the case here. But those folks also don't generally become religious at the moment their kid hits 9th grade. By that time, he would have already had multiple exposures to both evolution and sex ed.

It's possible that he went to a K-8 Christian school, though, and then had to figure out what to do next. There aren't nearly as many religious high school options around here as there are for the lower grades.
