I would describe a 'police force' that can forcibly and summarily deport people to gray market gulags run by a self-proclaimed "what-if-4chan-had-a-meat-world-avator" dictator as pretty darn anti-democratic. Especially when most Americans find that the current immigration policy has gone too far[1,2]. But I mistakenly think democratic means responding to the will of the people.

(I included The Hill article not b/c I think it is a real news source, but to get ahead of the whole "pbs is lib fake news" angle)
"Anti-democratic immigrants" who are, if I interpret your (now flagged, preserved here) comment correctly, all Muslims? yes?
In other words, you believe that the practice of Islam in any Western country should be a crime and the police should be empowered to arrest and deport any Muslim they encounter? And that this is in line with Western democratic ideals and values?
