I hate this smug, self-assured bullshit. "I know I'm right, and people must be dumb or immoral to disagree with me." It's an easy way to go through life, because then you never have to think seriously about why your worldview is a justification for the mass invasion of the country my ancestors built with their bare hands.
None of these people can articulate a deportation standard that: 1) would satisfy left-wing critics of the administration's immigration policy; 2) would satisfy their intuitions about what "due process" is required; 3) would be workable given resource constraints; and 4) would permit deportation of most of the illegal immigrants allowed under Joe Biden's administration. They want to nullify the results of a democratic election. It's that simple.
