Obama's administration also had harsh immigration policies, especially in his first term. Just not cruel, the way Trump's were. Biden was a part of that administration so on top of that you also have the heavy pressure of the media and the GOP, and a border patrol who are gung ho. Even if, as some say, that is not a whip, it's still an awful image. Even worse is that a majority of this country would gleefully hold that whip themselves if they could.
America has absolutely decimated Haiti, many times over. If we owe any country it's them. Yet we see just how little respect they get from us.
