So, Alberta separatists say they've have enough signatures for referendum. Sigh. 📣 My take on their regressive & divisive rhetoric: thewalrus.ca/albertas-sep... via @thewalrus.ca To call this language a dog whistle is an insult to dog whistles.

Given how U.S. is unraveling in so many ways – a dysfunctional and evil force reviled both domestically and internationally – hard to believe Alberta government still embracing a MAGA inspired agenda.
