It seems to me, that it allows bigots to silence the turquoise alert, but keep the amber alert on. That way, they’re not bothered by missing “less-than-human” alerts. It makes no sense to me to make another alert type. Either we treat all people groups as equal humans, or we don’t deserve to be part of society. There is no in between. But… maybe I missed something in the linked site.
They may be. But “they” haven’t, so it continues.
