Come on - it’s clearly a loss for some and of benefit to others. Just read the posts - we each have our own opinion, and I will not even give you mine (though I’d like to

). We should respect the opinions of others, even if we do not understand them.
Since it is optional, as has been shown in the GIRM, all you have to do is find a parish and/or Mass that includes that part of the sign of peace (if that is your style) or omits it (if that is your style).
I know that if I attend Mass at my parish, there will be handshakes, hugs, kisses, and laughter continuing into the Agnus Dei. I also know that if I go down to the local Dominican Priory for Mass, that will not occur.
I attend Mass accordingly. Was that so difficult?
