I mean 20-50% on top of income tax. Putting your money where your mouth is. That percentage should not be too much for anyone truly passionate and willing to make some sacrifices.
Steal from the rest of society? Would you cop yourself on. Governments levy taxes and use that tax money to fund things that they think will benefit society. A la carte funding of the bits you think are worth funding is not a workable proposal. The Irish government funds lots of things I don't agree with but characterising that as theft is ludicrous.
