So...
If I poop in a bucket, place a sunflower in there, and call it art, do I qualify for govt funding? In other words, do I deserve your tax dollars for pooping in the bucket? What if I claim discrimination because the local university or city art society won't fund my bucket pooping?
I would argue no, that sort of thing does not deserve tax money. But who sets the standards, if not the govt agency tasked with spreading around some tax money (the money you worked hard for and gave to the govt) with the intent to foster a variety of artistic expression?
Someone has to set the standard, and govt funding of the arts is to ensure that artistic diversity survives what can often be brutal peer repression. So while there must be standards, those standards must be loose enough that some money goes to artistic endeavours that are outside the mainstream.
I don't trust YOU to make that decision, and if it was my decision I'd keep the tax dollars and buy a painting from a student at the local art school. But that doesn't help the "artist" who is trying to get tax dollars to poop in a bucket, and that's really what the question is all about. Who decides if pooping in a bucket should be funded as "art".
