means A space—physical or social—where people expect to be free from criticism, harassment, or ideas that challenge their beliefs.

from The term traces to 1960s–70s activist and therapy circles, where it described literal spaces (meetings, shelters) where marginalized people could speak without fear of violence or exposure. It migrated into workplace and campus policy language through the 80s and 90s, then exploded in the 2010s campus-politics debates, where critics stretched its meaning from 'free of physical threat' to 'free of discomfort,' which is the sense the modern, eye-rolling usage mocks.
