It's not about cherry picking ideas, it's about understanding where your ideals come from. Most left-wingers do profess a 'right to healthcare' which somehow grants people claim over other people's stuff. I'm trying to understand the inconsistency being applied between a 'right to my money/possessions' and a 'right to my body organs'.

Explain your premise for WHY redistribution of wealth is acceptable. THEN, explain why that premise can't be applied to redistribution of health, kicking intelligent kids out of classrooms so that we can dedicate more time to the slower ones etc. If you can't do this, if your premise has multiple natural sequitors, then you don't have a consistent worldview.
