It is time to cancel Mecca and shame any Muslim who makes a pilgrimage...

Mecca is where Muslims believe the Qur'an was first revealed to Muhammad. Muhammad did not try to abolish slavery, and bought, sold, captured, and owned slaves himself I would also note that unlike most other religions which have rightfully evolved, Islam has never preached the abolition of slavery as a doctrine.

We also need to cancel many indigeneous folks...Members of five Native American nations, the Cherokee, Chickasaw, Choctaw, Creek, and Seminole Nations (known as the Five Tribes), owned black slaves. They were located outside the territorial boundaries of the US (modern-day Oklahoma), and these sovereign nations were not affected by proclamations or constitutional amendments. Instead, separate treaties had to be made between the US and these Native American nations to free enslaved peoples.
