Good article, thank you. It is good to see this and Jo Bartoch's article this week pointing out the very class based issues of this activism. It is the new acceptable snobbery, and you dig into it for two minutes to find the ageism, homophobia, racism, and religious intolerance all tucked down inside as the 'acceptable' way to hold such views.
It also, interestingly from multiple court cases, tends to often run alongside quite fantastical limited competence and limited functional intelligence/being extremely poorly informed, but one hell of a lot of small social circle signalling and mindless recycling of current fad language.
