It's a stupid path for her to go down because there's nothing good at the end of it. She is Hillarysplaining. Trans women don't need Hillary's opinion on this, and women under the age of 80 don't need her opinion on, frankly, anything. She could just as easily have said, "I'm really old and I live in a New York Review of Books bubble and the world has passed me by."
But I don't see it as TERF. Just tonedeaf and patronizing and oblivious in her patented way of the last 30 years. She sucks; this isn't the first clue.
