Here's a potential litmus test for Lemmy users

Ask them if they've read about Dessalines, and ask their thoughts on them?

Whether it be the Github user who founded Lemmy, with his Anti-American and Marxist Leninist essays,

or

the Haitian general who fought against the French in the Haitian Revolution, and thus had a hand in genociding many remnants of the white slave-owners... to create the first abolitionist country.

Just ask what they know and what they think of him?
