OK, all you're doing is playing the semantics game here. Instead of advocating perfect 'equality', you're advocating partial 'equality', which is the same thing but even more inconsistent.

I think that you're thinking on too high a level, without understanding where left-wing opinions are derived from in the first place. What you need to do is explain what natural rights are, and then derive your political understandings from there.

Left-wingers tend to believe in a level of equality because of 'social' rights like a right to an education and a right to health. If you accept that somebody's right to my money can be greater than my own because they have a right to health (and can't afford healthcare), why would this right not extend to my body organs which I can function without, when they can't get a body organ?

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'.

I completely agree with you that most people pick an ideal that works in their favour, but the accusations of greed almost always come from the left. Acting in your own self-interest and calling others out when they do the same is very inconsistent.

If you use a majority opinion as a reason to legitimise a decision, that's argumentum ad populum. In the past, the majority have traditionally supported persecution of the few. If you don't believe me, go and read into apartheid or the civil rights movement.

I'm not sure that you're capable of refuting anything with that nonsense. You've not understood my argument, so I'll ask in simpler terms:

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.
