overanalyzing hand-holding

Sweet article, A Simple Show of Hands, on what the simple gesture of holding hands suggests these days. Some snippets:

“Hand-holding is the one aspect that’s not been affected by the sexual revolution...”

Nowadays hand-holding has attracted the interest of scientists who are studying its effects on the body and mind...

Usually it connotes something innocuous and sweet about a couple and their relationship...

Someone should write a follow up piece on what hand-holding connotes (and incites?) in Orthodox communities (like CH): Scandalous? If so, why? And why the sudden prevalence of the gesture in public? (I think it's cute.)
