Right-wingers are, in fact, creating 'safe spaces' on college campuses, in Facebook groups, and so on. For my part I see the need for safe spaces in some contexts but I do feel the concept is being taken too far (one article I read recently claimed that students at various colleges are now demanding racial segregation as a form of "safe space" which I find utterly ridiculous). I'm not exactly sure where the boundary resides between acceptable safe space and "taken too far" or how to theorize it, though.
