Mekka Okereke is an engineering director at Google, and a powerful voice on Mastodon where he educates his readers about structural and systemic racism in America. His threads for Black History Month—which necessarily focus on U.S. white history (“I don’t like talking about Black history. Americans know Black history.”)—will prove eye-opening for most Americans.

Two years ago he created a megathread linking to all of his previous threads, referencing them annually with updated commentary. He kicked off 2026’s Black History Month thusly:

This Statue of Liberty thread is especially relevant this year, when everyone is trying to pretend that US fascism against immigrants is something new, by ignoring the ongoing US fascism against Black people. People love to erase or ignore Black suffering. But we’re still here, and we stubbornly refuse to be erased or ignored.

From that Statue of Liberty thread:

Try this: Ask your white US friends what the statue of liberty celebrates.

Now ask your Black friends. Or French folk of any color.

His February 2 thread is about Generational wealth:

Q: “Why don’t Black people build any generational wealth? Newer immigrant groups seem to be doing just fine? Must be a lazy and shiftless people!”

A: Because for most of US history, white folk have intentionally destroyed the wealthiest Black neighborhoods in the US and stolen all the wealth. […]

I still run into New Yorkers that go to Central Park every week, but have never heard of Seneca Village.

Each day brings a new, remarkably informative thread about our history. For convenience, here are links to each collection of threads in that megathread:

February 1–4 • February 5–12 • February 13–19 • February 20–25

I think these are a must-read (and Okereke a must-follow; also on Bluesky), especially if you think you know your American history.
