DH had a poster on the wall of his office when he was the school psychologist and director of special ed in a public school district. "Sticks and stones MAY break your bones, but words will ALWAYS hurt you. Be kind." I, of course, had always heard the opposite and so this made me consider the absolute effects of harmful words.
Today, it can be in person or on any form of SM. Not always so easy to brush them off. Definitely not an excuse to ever harm someone though.
Something to consider.
Sadly, many Americans today regard kindness and empathy as weakness. There's so much "othering" and dehumanizing of people who aren't in our immediate peer group. That message is so prevalent today.
