Yes, I was clearly wrong with that demand. I've seen many cases when penalty and a yellow was given for a handball in the box and that's what confused me at first.
p.s: Actually, I didn't make such a demand, but it sounded acceptable in my head, even if I didn't say it

Oh, and you were wrong too that every handball on the line is a penalty and a red card. As we've seen, only the deliberate handballs are. Still, it leaves the ref to decide what's deliberate and what's not.
