Group think is universal and nobody can ever truly understand another person's point of view. The absolute worst by a country mile are religious, but everybody is susceptible. Women rallying behind a fallen comrade and railing at men in general has been a thing since forever.

You may have noticed most men appear utterly clueless about women's issues and entirely disinterested in learning. Those in power are the worst - for instance, Black people have to figure out how to deal with white people, but not the reverse. Ditto for gay v. straight, non-Christian v. Christians, etc.

Part of belonging to a minority (or an oppressed majority, as in the case of women) is needing a working knowledge of the people who run things. The opposite is not true.

There is another problem, such as conservative Christians. They're a minority, but they might as well be living in a hermetically sealed dome as far as escaping their group think.

As the less powerful sex, women have always had to form social support groups. And a lot of their seems-to-be blindness turns out upon inspection to be justified.

I always wonder about people who harp about group think, given that most folks are blind to their own.
