I shouldn't have to say this, but here we are: The whole point of the Bill Of Rights is to limit what the government can do even when voters want it. Voters might want the government to put gay people in concentration camps; that's not allowed because everyone has a right to liberty.
So when you say, "voters want deportations" and thus all of this OK, you're being fundamentally anti-American. Like, you couldn't be more anti-American. Literally the country was founded on the principle that there can be limitations on the government's power. That was our main contribution to world history until the 20th century, and it remains our greatest contribution to the cause of freedom.
