Unlikely that "no one ever had a problem before" (I've been associated with a number of schools and that would be a first).

Assuming 'fundie' means religious (back in the day it was most commonly a mince for "developmentally retarded"), my guess is that the staff might well have found sapphic displays more outside their own (and therefore normal) experience and thus such displays would have been more noteworthy. An increase in the percieved (not necessarily actual) number of such incidents being likely to spark action.

[Humans are wired to take note of the unusual.
There is also a quote I need to paraphrase as the interwbby is resisting my efforts to find it;
_All men define themselves as normal and see others as monstorous to the degree each departs from that normalcy_]

yes but the fact that no one has ever had a problem before the gay people did it is homophobic

Unless the ban on PDAs excludes such between hetero couples, any claim of 'homophobia' is risible.

Extending the ban to hand holding seem excessive, but follows a common pattern of over response to a period of boundary pushing.
