woofgang - // For me its not about whether the artist knows or not but whether I know....I won't knowingly support someone whose lifestyle disgusts me. //
Although we do differ in terms of the art / artist side of this approach, I do understand your view, it is about feeling at peace with your own morality, and if it would bother you to listen to someone who you know is a dreadful human being, then no issue here, I simply don't share that view myself.
The reason I understand it though, is that I always pay the money for the collection at Mass, and we have individual envelopes so that the church can reclaim the tax.
I am happy to pay for the maintenance of my local church and parish, but when the 'Peter's Pence' envelope comes up, I tear it up, I have never given, and never will.
The money is used for maintenance of the upkeep of The Vatican, ad having visited, and seen a tiny fraction of the obscene wealth of the papacy, I would not add one penny to it, even though they will never know of my refusal, it makes me feel better.
I also refuse to give to 'Life' collections, because I think the right of a mother to decide the future for herself and her foetus is hers and hers alone.
