This community is so ————— . The members don’t feel comfortable to criticize each other.
I am looking for a word or phrase for the blank above.
Of course there might be political obstacles against freedom of speech. But in certain societies/communities there are also cultural obstacles too. Due to a particular culture, people are either too shy or embarrassed to talk freely. In such communities it feels awkward to speak freely or criticize others, even mild criticism. So people might talk indirectly without mentioning names. Even when there is no political punishment for that, they are not comfortable to talk freely criticizing their fellow members. So the environment/culture is very conservative.
Such communities can be contrasted with other communities in which people freely criticize each other.
I am looking to see if there is any word/phrase for such communities/societies/cultures/contexts?
I know the easiest way is to go by just saying closed or conservative culture. But I like to see if there is other words for such communities or for such form of behavior.
