IMHO, definitely NOT!
Political parties, churches, and other 'faith-based' institutions are all special interest groups ideologically supported by some members of the larger society who should be prepared to support them financially also, and should not expect those who do not share their political or religious beliefs to contribute to their upkeep.
As a taxpayer, I submit - sometimes grudgingly - to my taxes being used for purposes which the government conceives to be in the national interest, such as education, health care, and defence. Even though I strenuously disagree with some of the policies being pursued in these areas I recognise that they affect the entire population, and therefore cannot be funded privately.
However, where political doctrines or religious dogmas are concerned, I think it is utterly immoral for the State, or those who subscribe to such notions, to expect me and other taxpayers who disagree with them to fork out public money - OUR money - to bail out organisations which can't drum up enough support from their own adherents to keep going. They should cut their coat according to their cloth, or go out of business.
