I didn't say that Trump referenced returning Blacks to slavery.  I said that those references were all over the internet.  There were memes and others discussing that concept.  I have not known of Donald Trump making that statement but upon his being elected as President the internet was flooded with his statements about various immigrants having to return back to their respective countries, illegal immigrants being deported back to Mexico (which he did say those two things) and Blacks returning to slavery (which I never heard him say).  That's how crazy things went after his election.  I would never put words in his mouth that he didn't say but the tone of his election was so "anti-minority" that even returning Blacks to slavery was put out there.
