@Lockheart Sure, and if you haven't paid enough in tax you should also not get the operation or medicine you need. Don't give don't get, eh?
That depends on why you haven't paid tax. If it's because you're on a low income, obviously that shouldn't apply, because you've still paid whatever tax you were asked to pay (even if that was zero).
If however someone is a lifelong tax evader who has deliberately refused to pay tax on their high income then, ideally, they wouldn't be able to take from a system funded by public taxation.
I agree we need more organ donors but some of you really need to have a think about what you're proposing when you say you want to exclude people from healthcare because they have a different set of principles to you.
Nope. It's not because they have a different set of principles to me (or to anyone on the donor register). It's because they have a different set of principles to themselves depending on whether they are a donor or a recipient. Which is fundamentally wrong.
If someone is just opposed to organ donation or blood donation per se, regardless of whether they'd be the donor or recipient, that's legitimate.
What is absolutely not legitimate is to say that you will participate in a system - be it taxation, organ donation, blood donation, the rule of law, etc. - if it benefits you, but that you will not participate in it when you are asked to contribute to it.
You either subscribe to that system of belief, or you don't.
You can't only subscribe to a system of belief when it benefits you, and reject it when it has some cost to you.
