A hundred thousand illegal immigrants per month are being caught crossing into the US through the southern border.
No other liberal democracy - from Canada to Finland to Japan to Australia - would tolerate such a flood of illegal immigration. Not even remotely close. Canada freaks out when a couple thousand illegal immigrants cross into its territory from the US in a given month.
Holding illegal immigrants in detention facilities, because there is nowhere else to put them until they can be processed, is not the same thing as a concentration camp. Claiming that they're the same thing is a gross abuse of the term and its history.
