Autonomous space

An autonomous space or safe space is a social space which is restricted with respect to social relations, language, political views and/or behavior. For example a club or forum may be limited to women, black women, etc.

Supporters say that the point of a safe space is to provide social space that is safe for marginalized people to freely communicate and express ideas. Opponents argue that it limits free speech and creates an echo chamber of concurring opinions, or even is discriminatory against certain groups like white men.

Others may offer refuges even from talk considered traumatic or prohibit events or persons whose presence might, for some, make a campus not safe.
