Some of these types are afraid that government involvement which appears to favor Christianity creates a "theocratic" environment where non-Christians would suffer discrimination or loss of self-esteem. A bit of a stretch, perhaps. Of course, the "establishment clause" only referred to preventing one Christian denomination from becoming the official "state church" (through an act of "congress") linked with dogma-specific loyalty oaths and citizenship, voting rights, etc., depending on membership in that one denomination. All the schools in the 1770s and 1780s had some type of religious orientation or instruction with Christianity, of course, forming that context.
