If they are a law-abiding citizen and are merely undocumented (which at the most is a civil violation not criminal) why not just give them a deportation order instead of arresting them? Then simply give them time to get their affairs in order and self-deport. If they do not comply, then it can be criminal. Why the necessity of immediate arrests as a standard?
Well, we know why. You are guilty of the thing you accuse me of...
I am not "opposed to any attempt to reverse a barbarian invasion". I am opposed to characterizing entire ethnic groups and people with a specific undocumented legal condition as a "barbarian invasion".
Team Trump requires that characterization because they can only morally justify their despicable actions when everything is a "war" and raping our women and children is an imminent threat every second until every deportable brown person, muslim, or "person who disagrees with Israel" is removed by force or by government execution.
Like I've said, this sentiment has been around since 2015. A bunch of neo-reactionary race-baiting midwits trying to remake "liberty and freedom" into xenophobic white nationalist pride with a dash of idolatrous Christian gobbledygook.
"Team Barbarian" are those similar to yourself promoting ethnic hatred and supporting government tyranny.
It's kind of a bore fest, to be honest. I miss arguing with economists, anarchists, and Calvinists.
