I am in support of your “little theory” and felt the exact “abuse” you write about. I wondered what happened to all the adults in the room? I found too often Twitter users didn’t debate content but only their message. Reply with petty insults and you win Twitter. So the initial town square hope I did have diminished over time. As you can see you, I had an experience on Twitter exactly as you described. I don’t have time in this beautiful World for that. I’m done with Twitter. Having said all that, you were one of my fav Twitter accounts. Always, insightful and always “the adult in the room.” Thanks for that.
