It is not like the internment camps the Japanese Americans faced during wartime.
You're right, it's worse because those camps did not separate parents and children. Here's a relevant perspective from someone who was in one of the Japanese-American camps. It's also not a response to a legitimate crisis: while there is seasonal fluctuation, the number of crossings is much lower than it was in the early 2000s (when there were no such camps).
I know this is somewhat collateral to the conversation so I'll leave it there.
