Although I don't want to turn this into oppression olympics, and at the risk of getting downvoted heavily, I want to point out that mass deportation of Hispanics wouldn't compare against hundreds of years of slavery of African Americans, forced mass migration and slaughter of Native Americans and the placing Japanese Americans in internment camps.

This is in no way saying "its not that bad of a policy" its still a horrible thing to propose, but saying "American policy tilt harder against one particular race than it ever has in the past" is ignoring a lot of history, unless you're talking about very recent events.

No, he proposed deporting illegal immigrants, which happen to be predominantly from Mexico. Many people of other backgrounds who are in the US illegally will be deported as well.

It's interesting that a presidential candidate can differentiate themselves from other candidates (and receive so much hatred) by stating that they will enforce the law when elected.

Making everyone obey the law is not tilting policy against one group just because that group has abused it disproportionately.

He wants to enforce the law. Hardly the worst thing a politician could say (in fact, saying he wouldn't enforce the law would be much worse, IMO).

Also, your first point isn't entirely correct; there already is a wall; Trump just wants to extend it (again, to enforce the law).
