Hello, this is my first post so go easy on me if i make any mistakes.

My question is what does Islam have to say about the horrible act of slavery and slave trading of any sort.

I am a strong believer in equality and freedom for each individual being on this planet (past, present, or future).

Also, what does Islam have to say about racism and hatred towards different cultures.

(Just in case : I'm not implying, blaming or pointing fingers at anyone of any religion or race.)
