Earlier quoted context omitted.
I'd be curious to see an explanation of why just knowing about jury nullification would disqualify you from being on a jury - obviously if you intend to nullify or "helpfully" inform the other jurors about nullification you should disclose it and therefore be disqualified, but I do not see how knowledge of nullification counts as something that should disqualify you if you have no intention of nullifying.
I didn't say it would legally disqualify you, just that it would prevent you from doing jury duty properly.
Knowing that I could nullify does not in any way prevent me from properly concluding a verdict based on the laws that are in place.
It's only if I choose to actually nullify that I'm not doing jury duty properly, but the knowledge of nullification as far as I can understand in no way prevents me from doing jury duty properly.
