My only substack experience was when a transphobe was using it as a base to send attacks on me I reached out to them to point out this violated their T&S. They explained they were good with that but they'd love to give me lots of money to be on substack. So this seems on brand for them.

When that racist canceled observation of MLK day - the Tucson school districts stopped classes and we all learned about King, his messages and sang We shall overcome.
