This happened in SF, but there are analogous events happening in all sorts of institutions (typically less egregious but trending in that direction) all over the country. Because this is a symptom of an ideology that isn't limited to SF even if it's particularly potent in SF. With respect to "but whatabout right-wing groups?!": we don't have to worry about one or the other because woke progressivism and other far-left ideologies fuel right-wing groups; combatting left-wing extremism and restoring moderate views will marginalize right-wing groups as well.
