My bestie went to college in Ithaca so I visited in the early 70s. I was uncomfortable even then. The radicalization had begun. After freshman year, she totally changed and we never had contact again.
What a shame you two fell apart. How sad. Sorry to hear that.
One of my wife’s dear friends went whacko when Trump got elected and started marching in “Resist” parades. She went completely nuts and was always recruiting my wife to the dark side. May wife told her to stop it, but she wouldn’t, and several months later that was the end of that friendship.
That was in the SF Bay Area where that type of person is very common.
