Like they secretly hold mostly right wing views, but they want to hang out with the cool progressives. One of my ex friends blamed Corbyn for everything, even Brexit??? Another now posts anti Muslim stuff on FB regularly. A third is now a full on ecofascist who will just rant about black people like he's my demented grandma.
I have never met a "moderate centrist" who erred on the side of the left. When they decide to take a position it is always the conservative position.
