Bricks assembled form a wall. Sarah Ahmed, a lesbian activist of Pakistani origin, in her book Vivir una vida feminista (Ed. Caja Negra - 2021) exposes the different “brick walls” that people who are not white, not male, not heterosexual, not cis, not without disabilities, and who are most often responsible for the work of diversity, constantly come up against. How to build new bricks for new walls? Walls that do not collide, walls that do not divide or create borders. Rather, they are porous walls that protect, like the walls of a house that protect against bad weather.
