So he only meant putting gays & lesbians behind metaphorical electric fences until they die.
"I figured a way out, a way to get rid of all the lesbians and queers but I couldn't get it pass the Congress – build a great big large fence, 50 or a hundred mile long. Put all the lesbians in there, fly over and drop some food. Do the same thing with the queers and the homosexuals. And have that fence electrified so they can't get out.
"And you know what? In a few years they will die out. You know why? They can't reproduce. If a man ever has a young'un, praise God he will be the first."
I don't think his follower did much to clarify the situation but identifed the problem: Straight people keep having gay kids. Clearly as long as that keeps up, the whole 'Death camp-get rid of gays forever' plan doesn't really stand a chance.
