Court bans man with low IQ from having sex

First, I excluded any moral perspective in my posting already in my very first four words by which I opened my posting.

You may not wanted to imply any morale here, but you did.

If Al sharpton started a comment with "I am not racist" but then launched into a racist rant his four words would be meaningless rubbish even if somehow he thought they were true.
The problem with the much discredited line of eugenics and racial purity is that it involves a moral issue and attempting to remove or exclude that moral angle simply makes it even more of a moral issue.
