“Baker argued that these events led students to prioritize identities over their faith in Jesus Christ.”
This is what I understand.
It is all a matter of degree.
In theory, virtually any self-identification (as a patriotic American, as a bus driver with an immaculate driving record, or even as "McDonald's Employee of the Month") - when taken to an extreme - could overshadow one's self-identification as a Christian.
But the preacher here is straining at gnats, and probably ignoring far graver matters.
I seriously doubt whether - in the case at hand - there was any concrete danger of the autistic children viewing "Autism Week" as any sort of "exaltation."
