Few here, and few progressives overall advocate for dispensing with immigration enforcement. Most deeply reject the wanton, indiscriminate and violent manner in which the current regime has carried out its practices. But the mischaracterization of this stance is a favourite straw man of the right.
The borders are enforced quit making up lies. In United States of America we still extend due process because that allows us to punish actual criminals. Instead you want to label everyone and deport them to a safe distance but do not want to actually punish anyone with the law or determine innocence. You have no respect for any law, and just use your own ideas of how things should work. So what is the point of the laws and punishment system if we can’t use it? When you just deport someone without due process you’re letting the “illegal” off the hook without consequences. But you know this, hence your phrasing.
