The only abuse I see is laypeople manhandling the Body of Christ as if they were passing out hors d’oeuvres.
I have never seen a "layperson" Eucharistic Minister behave with anything other than deep reverence when handling the consecrated host(s) or wine. The "manhandling" is a figment of your imagination.
And receiving "in the hand" is no less reverent than receiving "on the tongue". It's basically all skin contact. I seriously doubt God cares.....it is the reception that matters.
