For numerous reasons, a very horrible line of thinking IMO.
I remember some time ago North Carolina "man of God" (AKA minister) had the same line of thinking, but it wasn't for poor people who wouldn't get off their butt...
“Build a great big large fence 50 or 100 miles long,” Worley said according to the video posted on YouTube. “Put all the lesbians in there. Fly over and drop some food. Do the same thing with the queers and the homosexuals. Have that fence electrified so they can’t get out. You know what, in a few years, they’ll die out. You know why? They can’t reproduce.”
Then you have the wackadoodle from the 40's as a prime example of when the government decides who gets put in "camps"...
