Half sibling (or uncle/aunt) inbreeding is considerably higher risk than first cousin interbreeding. Only sibling is worse.

I have 2 recessive things that I know I carry, thanks to genetic screening. If I boinked a half sibling, they'd probably be a carrier of 1 of them, and there's a 50-50 chance any resultant offspring would have the conditions.

(Neither would be fatal but both would be severe chronic things-- e.g. hemachromatosis.

There's probably other rarer recessive things that I'm a carrier of and don't even know about.

...you could take steps to assure safety first, thanks to genetic screening.

Sure, but A) genetic screening only knows about the common issues, and B) if you marry someone random and don't realize they're a half sibling, you might not bother with genetic screening.
