Slavery was 1 of the most popular metaphors used by white colonists during the Rev to describe their treatment by the British bc as enslavers themselves,they cynically understood other white people would immediately get that that freedom meant not being treated like you’re Black. https://twitter.com/kirstiealley/status/1347885367945527298
Using slavery as a pithy metaphor in a nation founded on actual slavery was insulting then and insulting now. To do so in the same week an insurrectionist flew a Confederate flag in the Capitol is absolutely abhorrent.
Also, I get people all trying to clown Kirstie Allie with your slavery and the Internet jokes, but the fact that you wouldn’t make these jokes if she’d used the Holocaust as a metaphor should be your guide that perhaps you shouldn’t do so here either.
