“Raising awareness” is a slippery phrase. It can connote empty shows of solidarity rather than actual work, like performatively changing a profile pic after a tragedy. There’s a good amount of reasonable critique to the effect that, say, breast cancer does not benefit from all this extra awareness, at least in the absence of any accompanying action. People know about breast cancer. But slavery, for those fortunate enough to have no experience of it, is often something people associate with the past.
