So, this is something I saw a few years ago at a retreat with Pema Chodron, a Buddhist nun. Yes, me, Monique - this isn't a copy/paste.
A woman told Pema about the anger and hatred she saw on Facebook. The woman wanted to know how she could counteract that sort of vitriol and ignorance. Pema paused, then said .... "Well, not on Facebook."
As we head into 2019, remember: You're not going to change anyone's mind or attitude by getting into an argument on social media. Save your energy for more useful acts, like being kind to others, hugging your dog, or studying underwater basket weaving.
