Hard to follow some of the quoting as not easiest at times on this forum, but while I certainly think Trump is making bigoted statements:
Trump looks to be blaming the Mexico government for allegedly sending criminals / rapists etc over.
I can't see in the quotes that Trump has implied that Mexicans are less than human - he is saying that the government is somehow ensuring that those who come across are criminals / rapists etc, but that is only covering those coming over, not all Mexicans, plus I didn't think that criminals were necessarily less than human, unless everyone in prison is less than human (I have a slightly different view on rapists).
