What modern cultural issues are closest to The Cailleach’s heart?
Being as She is, ancient enough to be apart from most modern world cultures, the Cailleach tends not to worry overly much about cultural issues. She predates the Picts and the Celts. She was there to greet the Fomorians and the Tuatha de Danaan. She has seen people come and go along with their cultures.
I would say that the biggest issues that have caught The Cailleach’s attention in modern times are not so much cultural as environmental.
