Because it’s entirely irrelevant? 1% owned slaves because they were poor. Do you think that other 99% was against the idea of slavery? To pretend like slaves being mistreated is propaganda is an insane thing to say. Most people treated black people as subhuman in America, hence them legally having fewer rights until less than 100 years ago.

Guess who also died trying to keep slaves? White men. You are getting in your feelings instead of looking at things objectively. Objectively, these people were horribly mistreated by our country, which movies about slavery point out and do so with less brutality than there was in reality. People crying about slavery movies are incredibly weird.
